Question

A solution is made by mixing one mole of volatile liquid (A ) with 3 moles of volatile liquid (B ). The vapour pressure of pure A is 200 mm Hg and that of the solution is 500 mm Hg. The vapour pressure of pure (B ) and the least volatile component of the solution, respectively, are :

Quantrex Academy · Accepted Answer

Correct answer: D. (600 ~mm Hg , A )

( aligned & P _ S = P _ A ^ o X _ A + P _ B ^ o X _ B & 500=200 1 4 + P _ B ^ o 3 4 & P _ B ^ o =600 ~mm Hg aligned ) As ( P _ A ^ o P _ B ^ o A ) is least volatile.
