For a dilute solution, Raoult's law states that

A

the lowering of vapour pressure is equal to the mole fraction of solute.

B

the relative lowering of vapour pressure is equal to the mole fraction of solute.

C

the relative lowering of vapour pressure isproportional to the amount of solute in solution.

D

the vapour pressure of the solution is equal to the mole fraction of solvent.

Text Solution

Verified by Experts

The correct Answer is:
B
`P_("solution") = P_("solution")^@x_("solvent")`
`(P^@ -P)/(P^@) = x_("solute")`
