Elementary Background

In thermodynamics the chemical potential (CP) of a component s in a system may be defined in various ways. The most common and useful definitions are
$$ {\mu _s} = {\left( {\frac{{\partial G}}{{\partial {N_s}}}} \right)_{P,T,N'}} = {\left( {\frac{{\partial A}}{{\partial {N_s}}}} \right)_{T,V,N'}} $$
where G is the Gibbs energy of the system, A is the Helmholtz energy, N s is the number of s molecules in the system, Tis the absolute temperature, P is the pressure, V is the volume, and N designates the set of numbers N 1, ... , N c, where N i is the number of molecules of the i th species in the system. The set N′ is the same as N but excludes the number N s for the species s.
