Second virial coefficient for a mixture of nonspherical molecules of arbitrary symmetry

摘要: The mixture and interaction second virial coefficients of a binary gas nonspherical molecules arbitrary symmetry have been calculated for set unlike force parameters which is obtained from the like interactions by using empirical combination rules. In calculation molecular anisotropy very general type has accounted. relative contribution each branch evaluated as function temperature. theoretical values coefficient compared with experimental data N2+A, N2+He, N2+H2, N2+O2, N2+C2H4, N2+C2H6, CO2+A, CO2+H2, CO2+N2, CO2+O2, CO2+CO, CO2+C2H4, CO2+C2H6, O2+A H2+CO. agreement between theory experiment satisfactory all systems. Numerical estimations temperature composition are given systems CO2+O2 CO2+CO.
