Construction of Vapor-Liquid Equilibrium Diagrams for a Nonideal System
a. Develop the constant-temperature x-y and P-x-y diagrams for ethyl acetate–benzene mixtures at 75°C.
b. Develop the constant-pressure x-y and T-x-y diagrams for ethyl acetate–benzene mixtures at 1.013 bar
Data:
\ln P_{ EA }^{ vap }( bar )=9.6830-\frac{2842.2}{T( K )-56.3209}and
\ln P_{ BZ }^{ vap }( bar )=9.3171-\frac{2810.5}{T( K )-51.2586}This mixture can be described by the van Laar equation with the parameters \alpha=1.15 and \beta=0.92 as given in Table 9.5-1.
