Two liquids A and B are mixed temperature T in a certain ratio to form an ideal solution. It is found that the partial pressure of A i.e., `p_(A)` is equal to `p_(B)`, the vapour pressure of B for the liquid mixture. What is 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)^(@))`
