Chemical potential
In
thermodynamics and
chemistry, chemical potential, symbolized by μ, is a term introduced in 1876 by the American mathematical physicist
Willard Gibbs, which he defined as follows: Gibbs noted also that for the purposes of this definition, any
chemical element or combination of elements in given proportions may be considered a substance, whether capable or not of existing by itself as a homogeneous body.

chemical potential
The chemical potential is a partial molar
Gibbs free energy , defined as µi = ( G/ ni)T,P,nj. It is a measure of chemical stability that can be used to predict and interpret phase changes and chemical reactions. For example, consider mixing ice and water. If the ice melts, the chemical potential of the water was lower than that of the ice. If the water freezes, the chemical potential of the water was lower.
