Chemistry Question on Raoult’s Law and Henry’s Law
The vapour pressure of pure liquids A and B are 450 and 700 mm of Hg at 350 K respectively. If the total vapour pressure of the mixture is 600 mm of Hg, the composition of the mixture in the solution is
A
xA = 0.4, xB = 0.6
B
xA = 0.6, xB = 0.4
C
xA = 0.3, xB = 0.7
D
xA = 0.7, xB = 0.3
Answer
xA = 0.4, xB = 0.6
Explanation
Solution
The correct answer is (A) : xA = 0.4, xB = 0.6.
