Thermodynamic Properties of Gas Mixtures

Thermodynamic Properties of Gas Mixtures.—The residual thermodynamic properties of a gas, that is the differences between the measured thermodynamic 

As in the case of liquids, it is possible to define excess thermodynamic functions for gas mixtures. The enthalpy of mixing of two gases at constant temperature and pressure, 

at low pressures the enthalpy of mixing is simply related to and d /dT. The higher-order terms, however, are rather involved functions of the virial coefficients of the pure components and the excess virial coefficients. 

From the relation between and the excess Gibbs free energy and excess entropy, G and 5 ,
