Abstract
The molecular theory for a pure liquid of r-mers formulated in a previous paper on the basis of the quasi-chemical treatment (the first approximation) has been extended to mixtures. The present theory takes into account nonrandom mixing of both holes and component molecules. A more crude formulation of a mixture based on the zeroth approximation is also presented for comparison. The expressions for the equation of state, chemical potential and internal energy are derived for the mixture. The excess functions of mixing have been numerically calculated so as to investigate the effect of nonrandom mixing on these quantities by comparing the first and zeroth approximations.
