Question

Components A and B are in vapor-liquid equilibrium. Initially, 1 mole of liquid (?? = 0.4) and 0.1 mole of vapor (?? = 0.7) are present.

a) What is the overall mole fraction of component A in the system initially?
b) 0.5 mole of A is then added and the system goes to equilibrium at the same temperature

and pressure. What is the final mole fraction of component A in the system?
c) Which of the following statements is correct in achieving the final state?
1. The amount of liquid increases
2. The amount of liquid decreases
3. The concentration of A in the gas phase increases
4. The concentration of A in the liquid phase increases
