Dividing this quantity by the number of moles in question gives the chemical potential.
Dividing this quantity by the number of moles in question gives the chemical potential. This quantity's natural variables are temperature and pressure. This quantity is equal to minus the log of the equilibrium constant times the ideal gas constant and temperature. This quantity is negative for spontaneous reactions that occur at constant pressure, while a complementary quantity meaningful for systems at constant volume and temperature is named for Helmholtz. For 10 points, name this quantity, whose change for a process is equal to the change in enthalpy minus the product of temperature and change in entropy.
