Benzene and toluene are ideal solutions. At 300 K, Ptoluene = 32.06 mmHg and Pbenzene = 103.01 mmHg. a) A liquid mixture contains 3 moles of benzene and 2 moles of toluene. If the pressure on the liquid mixture is reduced at 300 K, at what pressure (mmHg) will the first vapor bubble appear? b) What is the composition of the first vapor formed (yB)? c) If the pressure is reduced a little more, what is the pressure (mmHg) at the point where the liquid was last seen? d) What is the composition of the liquid at the last sight (XB)? e) At the point where 1 mole of mixture evaporates using Lever's rule; Find the pressure (mmHg), the composition of the liquid (XB) and the composition of the vapor (yB).
