Generalized property correlations for gases a. Lee and Kesler correlation b. Generalized second-virial-coefficient correlation 2. Extension of generalized property correlations to gas mixtures 3. Example 4. General procedure for calculation of U , H ,and S for liquids and real gases at any temperature and pressure Key Concepts 1. The generalized property correlations for gases provide a method to predict H R and S R from knowledge of T c , P c , and ω for nonpolar, non-associating gases. The concept is based on the theory of corresponding states and leverages the fact that H R
