= = = 6. A mixture of two compounds, A and B, has an azeotrope at T = 301.4 K, P = 136.94 kPa and xa = YA = 0.392. The vapor pressures of substances A and B at this temperature are 101.57 kPa and 86.42 kPa, respectively. To describe the properties of this mixture, use the two-parameter Margules equation and: a. Determine the numerical values of A12and A21which describe this mixture. b. Determine P and KA = YA/xa for the cases where xa = 0.2 and where xa = 0.6. =
