The second and the third virial coefficients in the lattice model of athermal mixtures of molecules of difierent sizes are calculated. Ail computations have been done for two-and three-dimensional simple square and simple cubic lattices.
We present expe&ent?l d&t of second virial~coeffidients of a&n at temperatures of 77.3.87.2 and 90.2 K. The results axe in excelledagreement with theoretical values. In recent years considerable progress in the determination of the intermolecular potentials of, argon and the other noble gases has
Scaling theory is applied to derive expressions describing the influence of polymolecularity on the second virial coefficient, A , , as obtained from osmotic pressure and light scattering measurements. Numerical values of polymolecularity correction factors are calculated for Schulz-Zimm and logarit
