QUESTION $3$

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 $80C.$ The nitrogen flow rate is $10\mathrm{.}0$ standard liters per minute. The gas leaving the bubbler is saturated with benzene and toluene vapors.

Draw a fully labelled process flow of the system.

Estimate the initial rates $(mo\frac{l}{m}in$ at which benzene and toluene leave the bubbler.

How will the mole fractions of benzene and toluene in the liquid change with time $($increase$,$ decrease, or remain constant$)?$ Explain your answer.

How will the mole fractions of benzene and toluene in the exiting gas change with time $($increase$,$ decrease, or remain constant$)?$ Explain your answer.
