The total vapour pressure of a binary so...

The total vapour pressure of a binary solution is given by `P=(100x_A+260x_B)mm Hg`
where `x_A` and `x_B` are the mole fraction of components A and B. This indicates that the :

A

vapour pressure of solution is less than the pure B component

B

vapour pressure of solution is more than that of pure A component

C

vapour pressure of pure A is 100 mm Hg and that of pure B is 260 mm Hg

D

the vapour pressure of pure A and B are 260 mm Hg and 100 mm Hg respectively
