Why is Gibbs free energy 0 at equilibrium?

The reaction is "at completion" so there is nothing spontaneous to drive the reaction forward or backward

Gibbs free energy is a measure of how much potential a reaction has left to do a "net" something . If the free energy is 0 that means the reaction has reached equilibrium and no work can be done.

When the gibbs free energy is zero, the reaction is at equilibrium because neither the forward nor the reverse reaction is favored.

At zero, there is no more work that can be done, and the reaction does not favor either the reactants or products. Thus, it is at equilibrium.

There is no more "free energy" to do work because the reaction is at equilibrium and so a foward nor a backwards process is favored. Think about a ball in a valley, if the ball is on an incline, it will roll down. However if the ball is at equilibirum or the lowest point of the valley, the ball will not move anywhere.
