Abstract

The limits of applicability of the Redlich-Kister, NRTL and LEMF equations when applied to heterogeneous systems are specified. These limits follow from the requirement of solvability of relations of the equality of activities in coexisting phases on the one hand and of the monotonous dependence of activity coefficients on the other hand.
