Question:

7.By measuring the equilibrium between liquid and vapor phases of a solution at 30°C at 1.00 atm, it was found that XA 0.220
7.By measuring the equilibrium between liquid and vapor phases of a solution at 30°C at 1.00 atm, it was found that XA 0.220 when yA 0.314. Calculate the activities and activity coefficients of both components in this solution on the Raoult's law basis. The vapor pressures of the pure components at this temperature are: pA 73.0 kPa and ps = 92.1 kPa. (XA is the mole fraction in the liquid and yA the mole fraction in the vapor.)
