Assertion :- If a liquid solute more vol...

Assertion :- If a liquid solute more volatile than the solvent is added to the solvent, the vapour pressure of the solution may increase i.e., `p_(s)gt p^(@)`.
Reason :- In the presence of a more volatile liquid solute, only the solute will form vapours and solvent will not.

A

If both assertion and reason are true, and reason is the true explanation of the assertion.

B

If both assertion and reason are true, but reason is not the true explanation of the assertion.

C

If assertion is true, but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

Correct R. Both solute and solvent will form the vapour but vapour phase will be richer in solute.
