Van't Hoff Equation

[Jasleen Kahlon]

The Van't Hoff Equation shows temperature dependence of K, but I'm still a little confused on what that means, and does the equation in any way connect to ∆H, ∆S, and ∆G?

deltaG = -RtlnK

and since deltaG = deltaH -T*deltaS, we can rearrange it to solve for deltaH and deltaS.

The Van't hoff equation relates the change in the equilibrium constant K of a chemical reaction to the change in temperature. It is derived from combining the equations deltaG = deltaH - TdeltaS and delta G = -RTlnK.

The Van't Hoff Equation is used to calculate K at different temperatures. In finding the K, you would assume that the delta S and delta H are not significant.
