Two components, A and B, were mixed forming a non-ideal solution and their liquid and vapor phases were allowed to equilibrate at 298 K and a pressure of 1 atm. The mole fraction of A in the liquid phase was found to be 0.380. The mole fraction of A in the vapor phase was 0.490. Calculate the activities and activity coefficients of both A and B in the solution on the basis of Raoult’s law. The vapor pressures of the pure liquids were P*(A) = 790 Torr and P*(B) = 600 Torr. Do these represent positive, negative, or no deviations from Raoult’s Law? Describe the intermolecular interactions that take place between A and B.
