Equilibrium Nitrogen is bubbled through a liquid mixture that initially contains equimolar amounts of benzene and toluene. The system pressure is 3 atm and the temperature is 80oC. The nitrogen inflow rate is 1.0 mol per minute, and the Nitrogen does not condense. The gas leaving the bubbler is saturated with benzene and toluene vapors.
(a) Calculate the vapor pressure of toluene and benzene for the gas stream leaving the system.
(b) Calculate the composition of the exit stream using Raoult's law for mixtures.
(c) Estimate the initial rates (mol/min) at which benzene and toluene leave the bubbler.
