Mam I have already lost my hope to attain the problems of thermodynamics in neet exm but after seeing your uploaded video I think i will not leave any sum as unturned ....thanku mam...I am grateful to you
You are really very nice teacher mam. I really like your videos. Mam my request to you is that please make maximum videos on trick's in physical chemistry. Just flush out the problem of Physical chemistry.
Mam in the last solved question.....I have a doubt. U took c2h6 as -x3 because it was taken from the reactant side, right.....so the value of c2h6 will be -x3, right.....but also the formula itself has product-reactant, that means , formula itself already has a -ve in it.....so doesn't the formula's -ve and -x3 comes out to be +ve??, Like shldn't it be +x3??
It's more than a month since this was discussed in my class but it's only now I understand even the most basic as to why it's Hf and Hc🤦 I can just tell how much our lessons lack infos that even if I read everything I still can't get how to solve such problems. This is what I always notice in my classes, they lack information, I wanted them to discuss everything from the very basic till whatever they have to. It's the only way for me to learn. Even if they say those were already discussed the past years but come on please we can forget things especially that we're forcing our brain to store many different information everyday😭 I can tell I was learning a lot more when I was 13-16 years (JHS) than now
Mam i have a similar question with me as you did the 2nd question in this vedio.... Calculate the standard enthalpy of formation of CH3OH. from the following data: (i) CH3OH(l) + 3/2 O2 (g) → CO2 (g) + 2H2O (l); ΔrH- = - 726 kJmol-1 (ii) C(s) + O2(g) →CO2 (g); ΔcH- = -393 kJmol-1 (iii) H2(g) + 1/2O2(g) →H2O (l); ΔfH- = -286 kJmol-1 in this case also we finally arrive at the equation C+2H2+1/2O2-->CH3OH here the enthalpy of oxygen is not given ...why cant we neglect the enthalpy of oxygen ...if we neglect i am arriving with a wrong answer
I am whole heartedly saying thank you so much mam 🙏. we were in confusion how to get good mark.we were in depression but as a light u came in our life .Thanks for ur dedication and hardworking for our future mam🙏💯
Mam this problem solve mam Calculate the standard enthaply of formation of methanol give that enthalpy of combustion of carbon , hydrogen and the methanol are -393.5KJ/mol , -393.5 KJ/mol , -285.83 KJ/mol . respectively . Mam this is the question plz mam solve mam
Madam there is mistake in the end of the video...i.e enthalpy of combustion example....you are not treating excess of oxygen....you took hydrogen instead of oxygen
