chemical potential
The work required (in J mol-1) to bring a molecule from a standard state (usually infinitely separated in a vacuum) to a specified concentration. More usually employed as chemical potential difference, the work required to bring one mole of a substance from a solution at one concentration to another at a different concentration, Dm = RT.ln (c2/c1). This definition is useful in studies of active transport; note that, for charged molecules, the electrical potential difference must also be considered (see electrochemical potential).
