Liquids ' A ' and ' B ' form an ideal solution. If the vapour pressure of pure liquids ' A ' and ' B ' are 40 and 90 cm Hg , respectively, at what pressure (in cm Hg ), the difference in mole fraction of ' A ' in vapour form and in liquid form will be maximum?

Answer:

60.00

Solution:

Concepts: Raoult's Law, Dalton's Law of Partial Pressures. Maximum difference occurs when total pressure $P_{t o t a l} = P_{A}^{0} P_{B}^{0}$ .

$P_{t o t a l} = 40 \times 90 = 3600 = 60$ cm Hg.
