Outline of Thermodynamics #3

Why does reaction free energy depend on pressure and the equilibrium constant?

Gibbs free energy depends on the equilibrium constant/reaction quotient as shown by these equations:
deltaGo=-RTlnK
deltaG=deltaGo+RTlnQ

To add on, you can tell that free energy, or ∆G, depends on the equilibrium constant K by observing the equation ∆G˚= -RTlnK. Also, the equilibrium constant will change if the pressure changes, thus ∆G depends on pressure as well.
