JEE Main 2015 Chemistry question
A solution at C is composed of 1.5 mol of benzene and 3.5 mol of toluene. If the vapour pressure of pure benzene and pure toluene at this temperature are 74.7 torr and 22.3 torr respectively, then the total vapour pressure of the solution and the benzene mole fraction in equilibrium with it will be, respectively:
Answer: (3)
Solution
In the liquid, and . By Raoult's law the partial pressures are torr and torr, so the total pressure is torr. The composition of the
