A liquid stream containing 52.0 mole\% benzene and the balance toluene at 20.0C is fed to a continuous single-stage evaporator at a rate of 1320mol/5. The liquid and vapor streams leaving the evaporator are both at 99.0C. 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? P=mmHg ybenzene=
