<chemistry> 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, __ = RT.In (c2/cl). 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).
