Gibbs free energy vs enthalpy
WebThe Gibbs free energy is a particularly important function in the study of phases and phase transitions. The behavior of G ( N, P, T), particularly as a function of P and T, can signify a phase transition and can tell us some of the thermodynamic properties of different phases.
