For the grand canonical ensemble, this quantity is given by Boltzmann's constant times temperature times the natural log of fugacity.
This quantity may be found directly for a component by the Widom insertion method. Negative S dT plus V dp is equal to the sum over all components of a system of mole number times this quantity in the Gibbs-Duhem equation. For the grand canonical ensemble, this quantity is given by Boltzmann's constant times temperature times the natural log of fugacity. An analogous concept that applies to electrons in a semiconductor is called the Fermi level, and this quantity measured at absolute zero is called the Fermi energy. The particle number derivative of the Gibbs free energy, for 10 points, name this quantity, the additional energy derived from the addition of an infinitesimal substance.
This quantity may be found directly for a component by the Widom insertion method.
