Consider a solution with ďĄ = 0.220 at 30°C in equilibrium with the vapor. The A vapor pressures of the pure components at this temperature are: p = 73.0 kPa and PB = 92.1 kPa. (a) Predict the vapor pressure and its composition at these conditions assuming ideal solution. (b) Experimentally it was found that the actual vapor pressure was 1.00 atm and y₁ = 0.314. Calculate the activities and activity coefficients of both components in this solu- tion on the Raoult's law basis.

Question
**Problem Statement:** Consider a solution with \( x_A = 0.220 \) at 30°C in equilibrium with the vapor. The vapor pressures of the pure components at this temperature are: \( p_A^* = 73.0 \, \text{kPa} \) and \( p_B^* = 92.1 \, \text{kPa} \). (a) Predict the vapor pressure and its composition at these conditions assuming an ideal solution. (b) Experimentally it was found that the actual vapor pressure was 1.00 atm and \( y_A = 0.314 \). Calculate the activities and activity coefficients of both components in this solution on the Raoult’s law basis.
