1) Benzene and toluene form nearly ideal solutions. At 20°C the vapor pressure of pure benzene is 74 torr and that of pure toluene is 22 torr. A solution consisting of 1.00 mol of each component is boiled by reducing the external pressure below the vapor pressure. Calculate (a) the pressure at which boiling begins and (b) the composition of each component in the vapor.
Benzene and toluene form nearly ideal solutions. If at 300K, P_ToI = 0.0422 atm and P_Benz* = 0.136 atm. Compute the vapor pressure of a solution containing 0.6 mole fraction of toluene. Calculate the mole fraction of toluene in the vapor for this composition of liquid.
