why is delta G equal to zero when a reaction is at equilibrium?

Since Gibbs free energy is a measure of energy available to do work, when the reaction is at equilibrium, no more work is being done and therefore delta G is 0.

No work is being done at equilibrium so the delta G value is 0.

We calculate delta G by doing G of products - G of reactants. If at equilibrium, the G between products and reactants doesn't change. Therefore, delta G = 0

Gibbs Free Energy is a measure of the reaction's tendency to proceed in a given direction (i.e. towards the reactants or towards the products). Since neither side of the reaction is favored at equilibrium, delta G is equal to 0.

Delta G is zero when an equation is at equilibrium because it has no tendency to shift to the reactant or product side but rather just stay as it is.

No work is being done at equilibrium and delta g represents the energy left to do work. Therefore, delta g is 0.
