What is the role of Gibbs free energy in determining the spontaneity of a reaction?

Accepted Answer

Gibbs free energy (ΔG) represents the maximum amount of useful work that can be obtained from a system at constant temperature and pressure. If ΔG is negative, the reaction is spontaneous and proceeds in the forward direction. If ΔG is positive, the reaction is non-spontaneous.
