On the generalization of the Van der Waals equation of state for mixtures

For pure fluids, the dependence of the Van der Waals parameter a on the temperature and density have been examined. The Van der Waals equation of state with an accurate hard-core part and temperature- and density-dependent parameters a_ij has been applied to fluid mixtures. The calculated p^E and V^I are compared with experimental data for AN₂ at 1–120 atm.
