Abstract
Thermodynamic properties of binary liquid mixtures containing simple species are calculated with the hard-sphere model originally proposed by Longuet-Higgins and Widom. No liquid mixture data is used. The only mixture parameter employed is k12, the deviation parameter for the geometric-mean mixing rule for intermolecular energy parameters. Very encouraging agreement with experiment is observed for both close-boiling systems and for mixtures containing a supercritical solute. A calculational scheme for mixtures containing the quantum gases hydrogen and helium is also developed with the same model.Keywords
