Q2. The constants in the Antoine equation are: xA=(PAPBPtotPB)PA=xAPA=yAP,yA=(PtotxtP) where P is in mmHg,T is in C and log10 is used instead of loge. Determine the vapour phase composition of a mixture in equilibrium with a liquid mixture of 0.5 mole fraction benzene and 0.5 mole fraction of toluene at 338K. Will the liquid vaporise at a pressure of 101.3 kN/m? (Harker et al, 1990)
