By means of measuring the equilibrium between liquid and vapor phases of a solution at 30 degrees C at 1.00 atm, it was found that xA = 0.220 when yA = 0.314. Compute the activities and activity coefficients of both components in this solution on the Raoult's law basis. Explain the vapor pressures of the pure components at this temperature are p*A = 73.0 kPa and p*B = 92.1 kPa. xA is the mole fraction in the liquid and yA the mole fraction in the vapor.
