Weak dipolar interaction in solutions: System: Benzene + chlorobenzene and toluene + chlorobenzene

Abstract In continuation of our earlier work, excess heats of mixing and volume changes of mixing have been measured for mixtures of chlorobenzene + toluene and chlorobenzene + benzene. The results have been analyzed both in the light of Balescu's theory and our modified approach reported earlier. Analysis shows that our modified approach gives better agreement and the systems should be treated as a mixture of polarizable polar and polarizable non polar molecules.
