4.3.18 VLE of Non-ideal Solution The activity coefficients of benzene (A) - cyclohexane (B) mixtures at 40C are given by RT In YA = br and RT In YB = ba. At 40°C, A and B form an azeotrope containing 49.4. mol % A at a total pressure of 202.6 mm Hg. If the vapor pressures of pure A and B are 182.6 and 183.5 mm Hg respectively, calculate the total pressure of the vapor at 40°C in equilibrium with a liquid mixture containing 12.6 mol % A. %3D
