MCQ

Relative lowering of vapour pressure is a colligative property because__________.

A
It depends on the concentration of a non electrolyte solute in solution and does not depend on the nature of the solute molecules.
B
It depends on number of particles of electrolyte solute in solution and does not depend on the nature of the solute particles.
C
It depends on the concentration of a non electrolyte solute in solution as well as on the nature of the solute molecules.
D
It depends on the concentration of an electrolyte or non electrolyte solute in solution as well as on the nature of solute molecules.

Answer

It depends on the concentration of a non electrolyte solute in solution and does not depend on the nature of the solute molecules.
It depends on number of particles of electrolyte solute in solution and does not depend on the nature of the solute particles.

Explanation:

Relative lowering of vapour pressure depends on concentration of non-electrolyte solute in solution and number of particles of electrolyte solute. It does not depend on nature of solute in both conditions.
