Why is vapor pressure lowering a colligative property?

Answer 1

Hope this helps yall

Vapor pressure lowering is a colligative property of solutions. The vapor pressure of a pure solvent is greater than the vapor pressure of a solution containing a non volatile liquid. This lowered vapor pressure leads to boiling point elevation.

Vapor pressure lowering is a colligative property because it depends on the number of solute particles in a solution, not their identity. The addition of solute disrupts the solvent's ability to vaporize, leading to a lower vapor pressure compared to the pure solvent.
