Definition

for the solvent $A$ in a solution, quotient of the absolute activity of substance $A$ , $λ_{A}$ (absolute activity), and that, $λ_{A}^{*}$ , of the pure solvent at the same temperature (ISO 80000-5: Thermodynamics) and pressure (ISO 80000-4: Mechanics):

a_{A} = λ_{A} / λ_{A}^{*}

pour le solvant $A$ dans une solution, quotient de l'activité absolue du solvant $A$ , $λ_{A}$ (absolute activity) par celle, $λ_{A}^{*}$ , du solvant pur à la même température (ISO 80000-5: Thermodynamics) et à la même pression (ISO 80000-4: Mechanics):

a_{A} = λ_{A} / λ_{A}^{*}
