If `P^(@)` and `P_(s)` are vapour pressure of solvent and its solution, respectively, `chi_(1)` and `chi_(2)` are mole fractions of solvent and solute, respectively, then

A

`p_s = p^@//X_2`

B

`p^@ - p_s = p^@X_2`

C

`p_s = p^@X_2`

D

`(p^@-p_s)/(p_s) = (X_1)/(X_1+X_2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`(p^@ - p_s)/p^@ =` Mole fraction of solute = `X_2`
