What does 0 Delta G mean

The system is at equilibrium at standard condition.The reaction is nonspontaneous at standard condition.A negative ∆g indicates that the reactants, or initial state, have more free energy than the products, or final state.When delta g is positive, the reaction is not spontaneous.Delta g is the symbol for spontaneity, and there are two factors which can affect it, enthalpy and entropy.
