Van't Hoff's Equation

[Daniel Yu 1E]

What is the significance of Van't Hoff's Equation?
In lecture Dr. Lavelle mentioned something about how it relates the K, chemical equilibria, to S, entropy, but how is that useful?

You might be thinking of the equation involving standard delta G's relation to the equilibrium constant K. Van't Hoff's Equation mainly relates a temperature change to its effect on K, if you already know the standard enthalpy change.

The Van 't Hoff equation relates the change in the equilibrium constant, Keq, of a chemical reaction to the change in temperature, T, given the standard enthalpy change, ΔH for the process.

The Van't Hoff Equation is used to find the temperature dependence of K and can be used to calculate K at a different temperature if delta H is known. Additionally, the difference between two Van't Hoff Equations can be evaluated to find lnK2-lnK1 (given that delta s and delta h are both constant).
