AN H-THEOREM FOR THE ENSKOG EQUATION OF A BINARY MIXTURE OF DISSIMILAR HARD-SPHERES

Within the context of a standardlike Enskog theory, we prove the exist ence of both a global and a local H-theorem for a system consisting of a binary mixture of dissimilar hard spheres. The semipositive charact er of the entropy production, in addition to previous results on the p roof of Onsager's theorem, exhibits the complete compatibility of our theory with linear irreversible thermodynamics.
