2 deltaG equations
What is the relationship between the equations deltaG=-RTlnK and deltaG= deltaH-TdeltaS?

Re: 2 deltaG equations
They both solve for the same delta G. You could also set these two equations equal to each other to derive the Van't Hoff Equation

You could use both these equations when solving for the change in the equilibrium constant, Keq, of a chemical reaction given change in temperature, T, given the standard enthalpy change, ΔH⊖, for the process.

Both equations solve for delta G, I believe it is just a matter of what information and values are given to you in the question for you to figure out which of the two equations to use.

Re: 2 deltaG equations
I believe G=-RTln(K) is for finding equilibrium constants, but the G=H-TS can be used for most other Gibbs free energy problems if you get/solve for enthalpy and entropy. Hope this helps.

Re: 2 deltaG equations
Both will help solve for the same delta G value! It mainly depends on what they give you to work with. Since they solve for the same thing, you can also set them equal to one another

Re: 2 deltaG equations
It depends on what information you're given to solve for G! If you're given the equilibrium constant, then you should use the first one. But if you're given the delta H and delta S, then you would use the second one. I believe they both should give you the same value!
