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 80°C. The nitrogen flow rate is 10.0 standard liters per minute. The gas leaving the bubbler is saturated with benzene and toluene vapors.
(a) Estimate the initial rates (mol/min) at which benzene and toluene leave the bubbler.
(b) How will the mole fractions of benzene and toluene in the liquid change with time (increase, decrease, or remain constant)? Explain your answer.
(c) How will the mole fractions of benzene and toluene in the exiting gas change with time (increase, decrease, or remain constant)? Explain your answer.
