Notes

μ_{B}^{& # 8854;} = R T ln λ^{& # 8854;}

where $μ_{B}^{& # 8854;}$ is a function of temperature $T$ at the standard pressure $p = p^{& # 8854;}$ .

The standard chemical potential depends on the choice of standard state, which must be specified.

In a liquid or solid solution, the standard state is referenced to the ideal dilute behaviour of the solute (substance $B$ ).

μ_{B}^{& # 8854;} = R T ln λ^{& # 8854;}

où $μ_{B}^{& # 8854;}$ est une fonction de la température $T$ à la pression de référence $p = p^{& # 8854;}$

Le potentiel chimique de référence dépend du choix de l'état de référence, qui doit être spécifié.

Dans une solution liquide ou solide, l'état de référence correspond au comportement de dilution parfaite du soluté (constituant $B$ ).
