A mixture of A(g) and B(g) is formed, where mole fraction of gas A is 0.8. Given : P_(A)^(@) = 400 torr, P_(B)^(@) = 200 torr Mixture of A and B obey Raoult's law.Then :

Answer»

Composition of first drop of condensate is `(X_(A) = 2/3)`
Total PRESSURE when first drop of condensate form is `1000//3` torr
The composition of LAST BUBBLE is `(Y_(A) = 8/9)`
Composition of A in vapour when mole FRACTION of A and B in liquid are equal `(Y_(A) = 2/3)`
