@@ChadsPrep I am an Indian and i should be honest with you. We have an entrance exams ( JEE Advanced ) which allows us into the IIT's and i am sure you know about it. Most of the teachers here in India are incomponent of teaching its level. And i am sure professor, you can teach upto that level. If you raised level till JEE advanced, believe me you will recieve huge crowd from India and you will be helping alot of students. Also this level will be automatically covered. Its my suggestion 🥰😍🤩

@ChadsPrep

Think about the combustion of glucose: C6H12O6(s) + 6O2(g) --> 6CO2(g) + 6H2O(g) The delta H is negative and delta S is positive which means it is spontaneous at all temperatures. Now consider the reverse reaction: 6CO2(g) + 6H2O(g) --> C6H12O6(s) + 6O2(g) This has a postive delta H and negative delta S and is not spontaneous at any temperature. But this doesn't mean it won't ever happen it just means it won't happen on its own. It will have to be accompanied by a huge input of energy from an external source. This is the reaction plants do during photosynthesis, and that big energy requirement is met by photons from the sun! Hope this helps!

Isn't weird if every reaction reaches the equilibrium, so why we count gibbs energy when in the equilibrium gibbs energy it's 0, it doesn't make sense, so reactions becomes neither spontaneous neither non spontaneous. I don't get it
@ChadsPrep
@ChadsPrep 5 жыл бұрын
You're right in saying that when every reaction reaches equilibrium that delta G will be zero. But the conclusion you come to seems to be then why do we care? And the idea is that if you have a system which is not at equilibrium but is spontaneous (negative delta G), then the absolute value of delta G under those conditions will tell you the maximum amount of work that can be performed by the reaction as it goes to equilibrium. This is very valuable information for say getting an idea of the maximum amount of work that could be performed by a combustion reaction (like in a combustion engine) as it goes to equilibrium. Ultimately, the more negative a delta G value the more energy that will be released as that reaction goes to equilibrium. Hope this helps!
@sportsport1654
@sportsport1654 5 жыл бұрын
@@ChadsPrep So how we can count total gibbs E of some reaction if every reaction achieve equilibrium at the end, that means we can count for some reaction more gibbs E depends at which point our rection is, but when our reaction achieves equilibrium we can't count the gibbs E because it becomes 0
@ChadsPrep
@ChadsPrep 5 жыл бұрын
So the further a reaction is from equilibrium the greater the magnitude of delta G and the more work that can be done in getting to equilibrium. But once equilibrium is reached the reaction has reached its minimum free energy and no more work can be done by the reaction.
