The vapour pressures of pure liquids A, B and C are 75, 22 and 10 torr respectively. Which of the following is/are possible values of vapour pressure of binary or ternary solutions having equimolar amounts of these liquids ? Assuming ideal behaviour.

Options:(select one or more)

Answer:

B, C, D

Solution:

$P_{A B} = \frac{75 + 22}{2} = 48.5 t orr P_{A C} = \frac{75 + 10}{2} = 42.5 t orr P_{BC} = \frac{22 + 10}{2} = 16 t orr P_{A BC} = \frac{75 + 22 + 10}{3} = 35.67 t orr$
