Question

why lowring of vapour pressure is not collective property​

Answer 1

Answer:

relative Lowering of vapour pressure is a colligative property as it sees the lowering of vapour pressure of a solution wrt solvent is a colligative property as it depends upon th quantity of solute rather than its nature.

Answer 2

Colligative properties of solution are those which do not depend upon the nature of solute but on the quantity of solute in a solution. So this takes lowering of vapour pressure out of the question because vapour pressure and it's decrease would depend upon the nature of solute
