Why is a reaction at equilibrium have G = 0?

If the system is at equilibrium, its free energy is not changing. Therefore, Delta G = 0.

This graph helps demonstrate the point if you are more visual or mathematical. Where you can see the forward and reverse reaction meet at a minimum. This minimum is equilibrium in this reaction and shows why since it is a minimum equilibrium would be 0.

At equilibrium, free energy equals 0, which means g=0
