why vapour pressure decreases by addition of solute ?

Answers

Answered by s02371joshuaprince47

Answer:

A solvent's vapor pressure will lower when a solute is added. This happens because of the displacement of solvent molecules by the solute. ... The lower number of solvent molecules at the surface means that fewer will evaporate, and thus the vapor pressure is lowered.
