Chemical potential is the partial derivative of this quantity with respect to the mole fraction, and an equation partially named for Helmholtz relates this quantity to the inverse square of temperature. Surface tension is the change in this quantity per unit surface area. This quantity is the negative of the ideal gas constant times the absolute temperature times the natural logarithm of the equilibrium constant. This quantity is also calculated as the enthalpy minus the product of temperature and entropy, and it is defined as the maximum amount of work that can be used by a system. For 10 points, name this thermodyna
