Question

Sum of vapour pressure is 2 ) ( P_{t O F G 1}=P_{A}^{*} x_{A}+P_{B}^{*} x_{B} )

# The liquids A and B have PÅ and Pg in the ratio of 1:3 and the ratio of number of moles of A and B in liquid phase are 1:3. Then mole fraction of 'A' in vapour phase in equilibrium with the solution is equal to: A 0.1 B 0.2 C 0.5 D 1.0

Solution
