ur a legend, the pandemic disrupted our education so much this year and probably next year which is my GCSE year. u literally saved me!

Thank you so much normally have trouble studying but you help SO MUCH.

THANK YOU SO MUCH THIS WAS SO SIMPLE TO UNDERSTAND!! I HAVE AN EXAM TOMOROW AND WAS FREAKING OUT SO THANK YOU THANK YOU!

Really nicely laid out and explained! Thanks a lot:)

literally explained in 3 minutes what my teacher could not in a week , you are a legend

for some reason i find myself to not be asked to revise for chem paper 2 tomorrow

Thank you soooooo much actually the first video that helped me with this topic

Your a legend I missed like 2 lessons in class and they were about reversible reactions and Le chatelier’s principle and I didn’t understand a thing , but with your videos everything is just made so clear , easy and simple to understand . Thanks

I’ve struggled a lot with understanding many popular people’s videos for science but carry on doing what you do because you’ve helped me so much and your doing an amazing job and I love your work

wow english people's accent when pronoucing french word is sooo nice and funny

I thought that I was going to fail my chemistry exam but I actually got a grade 9

this is my first time understanding this principle after watching lots of videos about it. Great and very recommended video

I really want to thank the team at cognito. Because of you guys i have been able to understand a few topics i dont understand in school u guys are doing a fantastic job and helping kids throughout the world please never stop!!!!

Your videos are as good as a person who's on top and you explain all the structures very clearly thanks

for the concentration: how can more ammonia be produced if the level of hydrogen is not increased as well? surely the hydrogen would be the limiting reactant right??

this sounds like @Udoka Fintelmann

You just explained that waaaaay better than my teacher

ur a legend, the pandemic disrupted our education so much this year and probably next year which is my GCSE year. u literally saved me!

really helpful especially with my second wave of paper 2 mocks coming soon. I was struggling with understanding the concept but this has made it so much easier now its time to seal the knowledge for the real gcses👍

the dislikes are the people who failed their science test

Tomorrow i have exam on whole unit 3 and your videos just saved my day. Great way to revise quickly

hi. for your last video on equilibrium, you said that heat encourages forward reaction, of equilibrium moves to the right, however, here you say that equilibrium moved to the right when temperature is decreased, which completely counteracts the previous statement? im a bit confused and would appreciate if you could answer my question before my exam tomorrow

I have a question. Can Le Chatelier's principle also be called "Factors affecting equilibrium"?

super helpful! you're doing a lot for students in lockdown ;)

Thank you for your video. However, I am a bit confused about the shifting of equilibrium. Wouldn't the equilibrium constant change if the equilibrium position shift?( Eg. If the equilibrium position shifts right, the denominator is larger, equilibrium constant is larger too) thanks 🙏

literally was so confused about this topic and this video cleared all my doubts. thanks!!

how did you summarize 270 mins of chem class in almost 4 mins

I was just doing some exam questions and I got stuck; I just didn't get it - I watch your video and immediately I understand. Thank You so much.

Thank you sooo much this was the one topic i have been struggling on for the past month and i finally understand

Youre amazing thank you!! I understand it so much more now :)

I'm a bit confused as to why that when you decrease temperature the counteracting change is an exothermic reaction which surely would mean it is losing even more heat rather than counteracting the temperature decrease. Other than that this was really helpful!

Your Explanation is too perfect ✨️👍👏

a few years later, still helpful, i will be using these videos for my mocks so thank you

He is a legend I was having problems with this and it got cleared

thank you so much, I was having huge trouble understanding this topic, but you managed make me understand it all in a 4 minute video! Thank you so much!

Thank you for explaining this very clear and concisely. Because of online classes, only reading my handouts makes it more confusing than it actually is.

oh golly, what a great video! This explained so much!😃😉

My teacher suggested your channel in the school meeting and the parents meeting. Keep up with the work !!! 🎉🎉🎉🎉🎉🎉🍾🍾🍾🍾🍾🍾🍾

Thank you so so much, I was really confused about how temperature affects the position of equilibrium before watching your video. I truly appreciate everything your team Cognito does. Thank you ones again.

If the temperature increases surely according to the Le Chatelier's principle, wouldn't the exothermic reaction be favoured to get counteract the increase of heat (since exo is heat exiting the system) so it decreases it back down to the normal tempt? since endo thermic means heat is being taken so it would just keep increasing the temperature instead????

Thankyou so much it really helped me to understand.

the Le Chatelier's Principle is very complex, I cant understand it

omg thankssss gsce in 2 months and pandemic disrupted my knowldge in chemistry

Great video

i love you maaaannnnn!!😭

Teachers should watch your videos and implement these types of teaching techniques so that we students can understand better.

i was able to understand most of the theory in this but i further want to learn, how does the particles in pressure balance out when changed ik when there is higher pressure the equillibrium goes to the lesser moles but why?? van u explain?

I have never understood this topic and now I finally do!!

Thanks. Really helped

Yes this was very helpful thank you soo much❤️

please, please, please do a level chemistry!! I love your videos so much!!

couldnt find this from freescincelessons so u saved meeeeeeeeeeeeeeeeeeeeeeeeeee

someone who can actually explain this topic tysm!

My teacher have a good taste of videos for us lol

I have my finals tomorrow and it's covering the entire IGCSE syllabus - all the way from states of matter to experimental techniques. Needless to say, I was feeling extremely stressed but this video helped me so much, THANK YOU!!

This helped me so much. TYSM

This helped me understand the concept as a whole as prior to this I had the wrong idea of what Le Chatelier's principle was.

This video is really helpful. My PEE's are starting next week and i am seeing ylur videosfor each topic (Bio,Chem&Phy). Its really helping me alot. THANK YOU

Thank you so much! I understand completely now

Hey dunno if you'll see this, but does this mean that each reversible reaction in a closed system will have a constant pressure and temperature it will always be at? As say the temperature is A when the equilibrium is in the centre, then you increase the temperature - the reaction shifts along the endothermic route, decreasing the temperature back down again. So the temperature has remained constant, your increase in temperature didn't really increase the temperature, as that was counteracted, but rather increase the concentration of the endothermic product?

Was helpful

legend

What about when u decrease concentration why does it not move ?

I was literally about to cry yesterday in class when we did this topic cause I wasn't understanding 😭this help so much🙏🙏🙏

Your videos are amazing. How many Maths videos are you going to do (you're on 92 right now I think). I'm wondering if, when you're done with those, you might move to AS or A Level in the four subjects. I know that it requires a lot of work to make these videos, so I understand if you can't. Thank you so much for these videos and good luck to reaching 100K #Roadto100K

Thanks, you're videos helped me soo much! please make videos on the solution of past papers of 2020 and 2021

I finnally understand this thanks to your well explained video. Keep up the good work!

I did find this helpful thank you very much

ap chem student here! thank you for saving me!

Cheers bro bless up }:‑)

excuse my language but i fucking love this channel

This really helped me to understand the concept! Thanks for the amazing vid !

nice! just curiuos what is the example of le chatelier's principle in home cooking?

Very helpful, put all 3 of freescience lessons into 1 vid aswell as explaining la chateliers principle

Thanks man I literally have a test in 1 hour

This guy just saved my life thank you soooooo much i really appreciate the effort ur putting on this channel

What happens if the concentration of the product decreases

lmao this is the first video that made sense and the tutor didnt sound annoying. thnx

What will happen if the Number of molecules are the same? Like A + B ----> AB. What effect would changing pressure would do in this case?

yesssssssssssssssssssssssssssssssssssssssssssss thanks so much

Thank you, Helped out a lot!

hi man thanks for the help. Keep it up. I have also recommended it to some of my friends about you.You deserve more subs

I wish that you can teach physics like just another mark in your channel

2 hrs before the exam! wish me luck

amazing video! this helped me understand it a lot better, thank you😁

absolute brilliance

Very helpful for my homework, love your videos and use them often.

Le Chatelier's Principle

Thanks! It really helped to understand a lot better

wow ngl this helps thanks.

nice

tysm bruv life saver

isn't it moles for pressure rather than molecules

YOU ARE MY SAVIOUR

you explain things so well !!!

Omg thank you

thank you

thankyou SO MUCH for ur help

love u mate❤
