Why does vapour pressure of a liquid decrease with addition of a non volatile solid solution

Hii mate
In a pure liquid, we can see that thereis more surface area available for the molecules to get evaporated. Therefore, they have more vapour pressure. On adding a non-volatilesolute, we cause the solvent molecules to get less surface to escape. Hence, the vapour pressure decreases.
