AQA A-Level Chemistry - Catalysis 

Got an A in my Chemistry thanks to you! Now i am going to study Medicine at University! Thanks for all of your help!

Finished my final chemistry exam yesterday, all I can say is thank you for all your help man, got me through a level chemistry. Its had its ups and downs but its been an absolute blast. Going to miss watching these badass videos but then I remembered I never have to work out how many Cnmr peaks does a benzene molecule have and stopped caring. Who doesn't guess that stuff anyway? But I will forever be grateful for showing me everything there is to know. You taught be to love chemistry, but I'm never doing it again. Fair well you genius and I hope you continue to help the less natural chemists like myself. Thanks again

Got AAA and couldn't have done it without your videos sir. I wish you all the best and thank you a million times over.

Dear Mr Rintoul For the past year I have been using these videos to learn various topics as well as revision... They have been extremely helpful and a key factor in my revision. Only believing I would get a C/B on the new AS spec exams I was very surprised to see that I got an A on results day! Thank you so very much for aiding me in achieving this as I couldn't have done it without you. You seriously are a living legend and wish every teacher could be as proactive and as helpful as you!! P.S. please can you do the a level new spec material as well as it would be very much appreciated Thanks again mate 👌

Please could you make a video on ligands, complex ions and the transition metal titrations? I am struggling with this and your videos are my main source of fully understanding topics! Thanks so much

could u do a video on transition metals properties and ligands complex ions ... that would be much appreciated ur videos are a superb btw

absolute corker of a video. take a bow son

Last minute revision before my exam today😟😂

I love you so much! Lol Thank you for saving the past two years of my life!! Last A2 exam in two weeks! The journey with chemistry will probably end here! Its been an honour watching your videos!!!

Got an A in AS due to your videos last year. If I get an A in A2 it will be because of you too!!

Just wanted to thank you so much for these videos, they are so helpful! Used them throughout AS and now A2, got my unit 4 exam in a few days so they are great for revision! Keep it up 👌

For the contact process where you use a catalyst for the reaction between sulphur dioxide and oxygen to produce sulphur trioxide. Isn't that catalyst heterogeneous, not homogeneous?

Thank You so much! Now 1 on Transition Metals and another on the specific metals please :P! Thank you so much though. These videos are great.

The last equation doesn't balance in terms of charges..... shouldn't it be 1/2 o2 + 2Co2+ + 2H+ → 2Co3+ + H2O

so when are the rest of the transition metal topic videos coming out cos at this point I'm desperate

Thankyou so much could you do chem5 2015 and chem4 2015 past papers plz?

Have you make a video for 3.2.4 the period 3 elements? Because I cant seem to find it.

do you have any more transition metal videos

I hate these blurry linesss...get it. I would fail without your videos so thank you for getting me into uni p.s I apologise for the joke..terrible.. I couldn't help it..

Please for the love of god cover the new spec topics, my teachers are crap and I need your help!

Love your videos i have as chem ocr exam tomoz

hi, your videos are really helpful to me when revising. I was just wondering, will you be making more videos on other A2 level subjects from the new specification?

@Elliot Rintoul .. Doesn't the transition metal chapter extend onto electro configurations and naming them or is this video out of date for the new spec? Brilliant video both ways

omg thank you. Amazing timing.

Hey there E Rintoul, your video lessons are really really helpful! Is there any chance that you'll be covering the rest of the A2 Spec before the exams this year?

In that very last reaction for cobalt, surely the charges arn't balanced?

Great video, thanks!

Hey mate, love your videos. When you uploading a video on KP?

is there a new a2 spec like there was a new as spec? And if so can these videos be used for it? Are you planning on making any videos on the new a2 spec?

where is the ligands and variable oxidation states video?

Hi. On the last question, for the reduction of Co3+, why is the hydrogen ion a product and the water molecule a reactant?

Hi Sir, is there a video on periodicity by any chance?

Thank you for the video- it is very helpful :).

thank you so much for your video, is the MnO4- ion "permanganate", or is it still correct if you write "manganate ion" in the exam

How come in the auto catalysis reaction intermediate step for 4Mn(ii) + MnO4- ..... why are 4Mn used?

what happened to the synthesis of methanol using chromium oxide omg

wrote it backwards - fukin hell that was funny, too much KET me thinks. lol brilliant vid

last question what example were you referring to the contact process of v205 ? is this the knowledge you had to apply ?

You know the first few reactions you said they were homogenous, aren't they heterogenous because at the beginning you described how heterogenous catalysis involved different phases so for example gaseous reactants and a solid catalyst and the first few reactions meet this criteria.

18:08 ESQ

do you have access to the hidden specimen papers for aqa

Are the first bunch in catalysts not in fact heterogenous catalysts because they are in a different states, you said contact etc are all homogenous?

where is the 3.2.4 videos

What software do you use to make your videos?

@Eliot Rintoul I hate to be one of those people but @4:46 you say that Vanadium oxide is a homogenous catalyst.. isn't it a heterogenous catalyst since its in a different phase to the reactants? That is also what it says on the specification.

Hi for the new aqa spec do we need to learn these equations

is catalysis AS or A2 cause its not in the AS book

last question you answered it wrong

👌👌
