Vapour pressure of a solution is ....

Vapour pressure of a solution is ______.

A

Directly proportional to the mole fraction of the solvent

B

Inversely proportional to the mole fraction of the solute

C

Inversely proportional to the mole fraction of the solvent

D

Directly proportional to the mole fraction of the solute

Text Solution

Verified by Experts

The correct Answer is:
A
For solutions containing non-volatile solutes, the Raoult's law may be stated as at a given temperature, the vapour pressure of a solution containing non-volatile solute is directly proportional to the mole fraction of the solvent.
