If temperature and pressure are held constant, the partial derivative of this quantity with respect to particle number is the chemical potential. Holding the same state variables constant, a homogenous substance will exist in its phase with the lowest fugacity, minimizing this quantity. For an electrochemical cell, the change in this quantity is proportional to the standard electrode potential, while its change can be found for a more general reaction by multiplying the universal gas constant by the temperature and the natural logarithm of the equilibrium constant K. If the change in this quantity is negative, the reaction is spontaneous. FTP, name this thermodynamic quantity symbolized G.
