P3.7. A gaseous mixture is made of two gases. The saturated vapour pressures over the pure liquids are p = 30 kPa and p = 40 kPa at temperature T = 320K. The mole fraction of the first component is equal to xe = 0.6. The mixture was isothermally compressed up to the moment when the first drop of liquid appeared. Find the particular pressure when this phenomenon occurred. The mixture may be treated as an ideal one.
