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?
