15.2 Le Chatelier's Principle | General Chemistry

HOW IS CHAD NOT MONETIZED??? He's literally the best! I've been having a hard time understanding what happens if the pressure is changed and this is the only video that helped me. Binging his other videos!

i just want to let you know that youre helping out people (like me just now) with your videos to this day

It is hard to get such quality lectures on YouTube. Very well explained and hope you will keep up the good work...

I am so thankful I found your videos! You are a great teacher, and I wish I had found you in gen chem 1! I love that you take the time to teach each aspect of the section. My professor teaches quickly and skips many small steps, so your videos help me actually learn the material.

Sir l know you are the only teacher who can clear away my all confusions relevant to my questions😢

You are truly a life savior ❤❤

I had to stop and applaud how beautifully simple you made everything right around the range of 3:40 to 4:40. Everything clicked so well it's like I could feel the neurons firing in my brain lol.

youre the best man, you explain things so well! THANK YOU!

Thank you so much!!!! Been watching all of your chem videos <3

Chad, In the last lecture you said that only temperature can change the equilibrium constant. So it is fair to say that when we are are changing the concentration of reactants and products, we are not changing the equilibrium constant but rather the reaction quotient. So when we change the reaction quotient, this shifts the reaction in a way that allows us to get back to the equilibrium constant which remains the same value because only temperature can change the equilibrium constant? (I hope this makes sense).

Hi, you said shifting to the right causes the Q value to go up, I thought it causes it to go down since it Q

Job well done ✅✅✅ God bless you

why would we shift Co to right and not left to decrease Co?

thank you so much for explaining the effects with temperature. I was struggling with that for a long time b/c I was confused how shifting T changes a rxn b/c it affects equilibrium. One quick question! how would you reconcile that delta G = -RTlnK but if you added heat in an exothermic reaction the delta G should be less negative, but according to the formula if you increase temperature the Delta G would be more negative? loving the new playlist!!

Sir can a Q become greater than Kc before we reach eq

best lecture✊

Dear sir you asked that change in conc of either reactants or products at eq doesn't affect the value of Kc but if we increase the conc of O2 here the reaction will go in forward direction and reverse reaction remains unchanged and after a second the consumption of extra O2 again rate of forward reaction also becomes slow down and both rates again become equal . In other hand if at eq we decrease the conc of Co the reaction will go in forward direction but in this case we have no extra addition of reactants or products but our normally present reactants at eq are consuming and in this case the rate of reverse reaction slow down and after a second both the rates again become equal sir how both these reactions could have equal value of Kc😢😢😢😢

Another Question, What if we decrease the pressure by increasing the volume? How would this effect the shift of the rxn?

this guys the goat

thank you
