By measuring the equilibrium between liquid and vapour phases of a solution at 30 °C at 1.00 atm, it was found that x_A
= 0.220 when y_A
= 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: p_A* = 73.0 kPa and p_B* = 92.1 kPa. (x_A
is the mole fraction in the liquid and y_A
the mole fraction in the vapour.)
