The azeotrope of the benzene-toluene system has a composition of \(53.2 \mathrm{~mol}\) per cent benzene with a boiling point of \(350.6 \mathrm{~K}\) at \(101.3 \mathrm{kPa}\). At this temperature, the vapour pressure of benzene (1) is \(112.23 \mathrm{kPa}\) and the vapour pressure of toluene (2) is \(88.27 \mathrm{kPa}\). Determine the activity coefficients for the solution containing \(10 \mathrm{~mol}\) per cent benzene.
