(choose chapter or problem)

By measuring the equilibrium between liquid and vapour phases of a solution at \(30^{\circ} \mathrm{C}\) at \(1.00 \mathrm{~atm}\), it was found that \(x_{\mathrm{A}}=0.220\) when \(y_{\mathrm{A}}=0.314\). 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: \(p_{\mathrm{A}}^*=73.0 \mathrm{kPa}\) and \(p_{\mathrm{B}}^{\star}=92.1 \mathrm{kPa}\). (\(x_{\mathrm{A}}\) is the mole fraction in the liquid and \(y_{\mathrm{A}}\) the mole fraction in the vapour.)
