ΔG (change in Gibbs free energy) is the best criterion for determining the spontaneity of a chemical reaction because it takes into account both the change in enthalpy (ΔH) and the change in entropy (ΔS) of the system. A negative ΔG indicates that the reaction is spontaneous, while a positive ΔG indicates that the reaction is non-spontaneous.
