Derive relation between Free Energy and Equilibrium Constant​

Answer 1

Question :

Derive relation between Free Energy and Equilibrium Constant

Answer :

The equation, ΔG = ΔG°+ RT ln Q, is derived on Wikipedia, under the subsection Thermodynamics. Remember, Q is the reaction quotient, which at equilibrium is equal to the equilibrium constant, K. Then you have your equation ΔG = ΔG°+ RT ln K.

Question :

What is the relationship between free energy and equilibrium constant?

Answer :

If ΔG° < 0, then K > 1, and products are favored over reactants at equilibrium. Conversely, if ΔG° > 0, then K < 1, and reactants are favored over products at equilibrium. If ΔG° = 0, then K=1, and neither reactants nor products are favored at equilibrium.
