16. The vapour pressure of pure benzene and toluene are 0.12 bar and 0.04 bar, respectively at 300K. A liquid mixture is composed of 1 mole, each of benzene and toluene. Q1 If the pressure over the mixture at 300 K is reduced at what pressure does the first vapour form. Q2 What is the mole fraction of benzene in the first trace of vapour formed ? Q3 If the pressure is further reduced , at what pressure does the last trace of liquid disappear ? Q4 What is the mole fraction of benzene in the last trace of liquid?
