By measuring the equilibrium between liquid and vapour phases of a solution at 30°C at 1.00 atm, it was found that xA = 0.220 when lA = 0.314. Calculate the activities and activity coefficients of both components in this solution on the Raoult's law basis. The vapour pressures of the pure components at this temperature are: pZ = 73.0 kPa and P~ = 92.1 kPa. (x, is the mole fraction in the liquid and YA the mole fraction in the vapour.)
