Definition

for solvent $A$ , standard absolute activity (standard absolute activity <in a mixture>) of the pure substance $A$ at the same temperature (ISO 80000-5: Thermodynamics) and at a standard pressure $p^{& # 8854;}$ (ISO 80000-4: Mechanics):

λ_{A}^{& # 8854;} = λ_{A}^{*} p^{& # 8854;}

pour le solvant $A$ , activité absolue normale (standard absolute activity <in a mixture>) du solvant pur $A$ à la même température (ISO 80000-5: Thermodynamics) et à la pression de référence $p^{& # 8854;}$ (ISO 80000-4: Mechanics):

λ_{A}^{& # 8854;} = λ_{A}^{*} p^{& # 8854;}
