Benzene and toluenen form nearly ideal solutions. At `300K,P_(\"toluene\")^(@)=30 mmHg` and `P_(\"benzene\")^(@)=100mm Hg`. A liquid mixture is composed of `3` mol of toluene and `2` mol of benzene. (a) If the pressure over the mixture at `300K` is reduced. At what pressure does the first vapor form ? (b) What is the composition of the first trace of vapor formed ? (c) If the pressure is reduced further, at what pressure does the last trace of liquid disappear ? (d) What is the composition of the last trace of liquid ?
