Two liquids A and B are mixed at temperature T in a certain ratio to form an idela solution. It is found that the partial vapoure pressure of A. i.e, `P_(A)` is equal to `p_(s)`. The vapoure pressure of B for the liquid mixture. Whatis the total vapour pressure of the liquid mixture in terms of `P_(A)^(@) and P_(B)^(@)` ?

A

`(p_(A)^(@)p_(B)^(@))/(p_(A)^(@) + p_(B)^(@))`

B

`(2p_(A)^(@)p_(B)^(@))/(p_(A)^(@) + p_(B)^(@))`

C

`p_(A)^(@)/(p_(A)^(@) + p_(B)^(@))`

D

`(2p_(B)^(@))/(p_(A)^(@) + p_(B)^(@))`
