at $3$ ants$)$ Nitrogen gas is bubbled through an equimolar liquid mixture of benzene and toluene

at $3$atm$(2280mmHg)$ and $80C.$ The flowrate of nitrogen is $0\mathrm{.}45$mol$\frac{e}{m}in.$ The gas leaving the

vessel is saturated with respect to all components of the liquid.

a$)10$ points. Draw and properly label a diagram of the process.

b$)20$ points. What is the composition of the gas leaving the vessel very soon after the start of

the nitrogen flow $($but after equilibrium is attained$)?$

c$)5$ points. What is the flowrate of gas leaving the vessel very soon after the start of the nitrogen

flow $($but after equilibrium is attained$).$

d$)5$ points. At some point, the mole fractions of the benzene and toluene in the gas leaving the

reactor will be the same. What is the liquid composition at that condition?
