This problem concerns vapor-liquid equilibrium mixtures of compounds Q and W. We know that:

• The vapor pressure of pure compound Q is 0.5 bar at 300 K. • The vapor pressure of pure compound W is 1.0 bar at 300 K. A) If a liquid is composed of 40% Q and 60% W and at 300 K, give your best estimate of the bubble pressure and composition of the first bubble of vapor that WOULD be observed IF Q and W formed ideal liquid solutions. Q and W do not, in reality, form ideal solutions. In reality, for vapor liquid equilibrium at 300 K, there is an azeotrope at P=0.9 bar and T=300 K, in which the liquid and vapor phase both contain 40% Q. Use this fact—as well as the vapor pressure data given above—to answer questions B and C. B) Give your best estimate of the activity coefficients of Q and W in the azeotropic mixture at 300 K. C) Give your best estimate of the bubble pressure and composition of the first bubble of vapor in equilibrium with a liquid that is composed of 75% Q and 25% W at 300 K.
