given values
Would we be given delta S naught and delta G naught or would we need to solve for these values in a problem and how is that calculation different than just calculating delta G or delta S? Thank you!

Re: given values
I don't know if we will encounter problems where we have to calculate the delta G naught or delta H naught in order to then use the Van't Hoff equation, but usually what we do with this equation is calculate K for a reaction at a different temperature when we know the delta H naught of a reaction, using the second form of the equation that we derived in class: lnK2/K1 = -delta H naught/R * (1/T2 - 1/T1)
As you can see, if we use that equation, we do not have to know or solve for S.

Re: given values
If we did have to solve for delta H naught, I assume you could do so either through the standard enthalpies of formation or even the deltaU = q + w formula.
Re: given values
I think it could be reasonable to have to solve for delta H naught or even one of the temperatures depending on the wording of the problem. The main use for the equation though is calculating K at different temperature values given a value for delta H naught, so ideally you would just be focusing on K and its dependence on temperature rather than solving for various parts of the equation
