Assertion:Lowering of vapour pressure is...

Assertion:Lowering of vapour pressure is not dependent on the number of species present in the solution.
Reason : Lowering of vapour pressure and relative lowering of vapour pressure are colligative properties

A

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

B

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

C

If assertion is true but reason is false

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
D
Lowering of vapour pressure is directly proportional to the number of species present in the solution. Only relative lowering of vapour pressure is a colligative property

Lowering in vapour pressure is a colligative property.

Knowledge Check

  • Relative lowering of vapour pressure

    A
    is a property of solute
    B
    is a property of solute as well as solvent
    C
    is a property of solvent
    D
    is a colligative property

  • Relative lowering of vapour pressure is a colligative property because

    A
    it depends on the concentration of non-electrolyte solute in solution and does not depend on the nature of the solute molecules
    B
    it depends on number of particle of electrolyte solute insolution and does not depend on the nature of the solute molecules
    C
    it depends on the concentration of non-electrolyte solute in solution as well as on the nature of the solute molecules
    D
    depends on the concentration of an electrolyte or non-electrolyte solute in in solution as well as on the nature of solute molecules
