Extension to Gas Mixtures
The generalized equations developed for ∆H and ∆ S in the last section may be extended to compute corresponding changes for a real gaseous mixture. The method used is the same as that developed in section 2.4 through the definition of pseudo-critical mixture properties using linear mixing rules:
Using the above equations pseudo-reduced properties are computed:
Further calculations of changes in internal energy, enthalpy, and entropy follow the same principles developed in the last section.
