Species A can react to species B in the gas phase (A --> B) with the equilibrium constant K.

A flow system feeds 2 mol/min of A to a reactor that reaches equilibrium. The total pressure in the reactor is maintained at 1 bar. K is equal to 7.

a. What are the mole fractions of A and B leaving the reactor?

b. What are the exit flow rates of A and B leaving the reactor?

c. A liquid that can absorb species B (but not species A) is added to the reactor. The Henry’s Law constant for absorption of species B by the solvent is 20 bar. The solvent may be assumed not to vaporize to any significant extent. What is the mole fraction of B leaving in the solvent?

d. If the flow rate of solvent entering the reactor is 20 mole/min, how many moles per minute of Species A leave in the gas phase?
