+ Problem Set 7 9 of 13 -/1 e Aliquid stream containing 49.5 mole% benzene and the balance toluene at 25.0C is fed to a continuous single-stage evaporator at a rate of 1120 mol/s. The liquid and vapor streams leaving the evaporator are both at 91.0C. The liquid phase leaving the evaporator is measured to be 42.5 mole% benzene. Physical Property Tables Pressure and Vapor Composition If the system obeys Raoult's Law and is in steady state, what are the operating pressure and vapor phase composition?
