Chemical Engineering: Raoult's Law

posted by .

A binary mixture of benzene and styrene is kept in a closed vessel at equilibrium such that both liquid and vapor phases co-exist. The total amount of moles in the vessel is 100. The total moles of benzene that is distributed in the liquid and vapor phases is 35. The temperature is kept constant at 112.7°C and the pressure at 815.8 mmHg.


Raoult’s law can be assumed to describe the phase equilibrium for both species and Antoine constants can be used.


Calculate the mole fractions in liquid and vapor phases and then use material balance to find the amount of the liquid phase.
