Second virial coefficient for a mixture of nonspherical molecules of arbitrary symmetry
Abstract
The mixture and interaction second virial coefficients of a binary gas mixture of nonspherical molecules of arbitrary symmetry were determined for a set of unlike force parameters obtained from the force parameters for like interactions. Empirical combination rules were used for this procedure, and the relative contribution of each branch of interactions has been evaluated as a function of temperature. Theoretical values of interaction second virial coefficients have been compared with experimental data for 15 binary systems. Numerical estimates of the mixture second virial coefficients are presented for CO2 plus A, CO2 plus H2, CO2 plus N2, CO2 plus O2, and CO2 plus CO.
