Question: Problem 4 . a ) Using the Pxy diagram, estimate the bubble - point pressure and the equilibrium vapor composition associated with a 4 0

Problem 4.
a) Using the Pxy diagram, estimate the bubble-point pressure and the equilibrium vapor composition associated with a 40 mole % benzene-60 mole% toluene liquid mixture at 100C.
b) If the mixture is steadily depressurized until the remaining liquid contains 25% benzene, what is the final pressure and the equilibrium vapor composition?
