A closed, nonreactive system contains species 1 and 2 in vapor/liquid equilibrium. Species 2 is

a very light gas, essentially insoluble in the liquid phase. The vapor phase contains both species 1

and 2. Some additional moles of species 2 are added to the system, which is then restored to its

initial T and P. As a result of the process, does the total number of moles of liquid increase,

decrease, or remain unchanged?
