For a dilute solution, Raoult's law states that

A

Lowering of vapour pressure is equal to the mole fraction of the solute

B

Relative lowering of vapour pressure is equal to mole fraction of the solvent

C

Relative lowering of vapour pressure of the solvent is equal to the mole fraction of the solute

D

Vapour pressure of the solution is equal to the mole fraction of the solute

Text Solution

Verified by Experts

The correct Answer is:
C
For dilute solutions, Raoults law states that relative lowering of V.P. `(Deltap//p)` is equal to the mole fraction of solute `(x_(B))`
`(Deltap)/(p) = x_(B)` or `(p^(@)-p_(s))/(p^(@)) = x_(B)`
