Assertion: Vapour pressure of solvent AA increases when a more volatile solvent BB is added. Reason : BB is more volatile therefore vapour pressure of BB is greater than that of AA.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

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

Step-by-step solution

Vapour pressure increases means the solvent BB is more volatile than AA and it has vapour pressure greater than that of AA.
