Two liquids X and Y form an ideal solution at 300 K , vapour pressure of the solution containing 1 mol of X and 3 mol of Y is 550 m m H g . At the same temperature, if 1 mol of Y is further added to this solution, vapour pressure of the solution increases by 10 m m H g . Vapour pressure (in mmHg)…

Question

Two liquids X and Y form an ideal solution at 300 K , vapour pressure of the solution containing 1 mol of X and 3 mol of Y is 550 m m H g . At the same temperature, if 1 mol of Y is further added to this solution, vapour pressure of the solution increases by 10 m m H g . Vapour pressure (in mmHg) of X and Y in their pure states will be, respectively–

According to Dalton’s law of partial pressure P T = P X 0 X x + P y 0 X y 1 4 P x 0 + 3 4 P y 0 = 550 1 1 5 P x 0 + 4 5 P y 0 = 560 2 On solving P x 0 = 400 P y 0 = 600
