## Abstract

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
where

$$
{\mu _s} = {\left( {\frac{{\partial G}}{{\partial {N_s}}}} \right)_{P,T,N'}} = {\left( {\frac{{\partial A}}{{\partial {N_s}}}} \right)_{T,V,N'}}
$$

*G*is the Gibbs energy of the system,*A*is the Helmholtz energy,*N*_{s}is the number of s molecules in the system,*T*is 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.## Keywords
