Gibbs free energy (G) combines enthalpy, entropy, and temperature to indicate reaction spontaneity: ΔG = ΔH – TΔS. A negative ΔG suggests a spontaneous process, while a positive ΔG implies nonspontaneity at that temperature. Gibbs free energy plays a central role in physical chemistry, biochemistry, and engineering, helping predict whether reactions or processes will proceed under given conditions.
