WebThe Gibbs free energy of a system at any moment in time is defined as the enthalpy of the system minus the product of the temperature times the entropy of the system. G = H - TS. The Gibbs free energy of the system is a state function because it is defined in terms of thermodynamic properties that are state functions. 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 …
