The vapor pressures of pure acetone and methanol are 165 kPa and 73.5 kPa, respectively, at 57.2oC. However, it was found that at equilibrium at 57.2oC and 1 atm that xA=0.400 and yA=0.516, which are the liquid and vapor phase mole fractions of acetone, respectively. Using Raoult’s Law, calculate the activities and activity coefficients of each component.
