why is there a depression in the vapour pressure when a non volatile solute i added to the solution

kintu kenneth

because the solute molecules occupy the surface of the solvent molecules and prevents their escape of in vapour state

When a non volatile solute is added to a solution...it occupies the surface of the solvent thea by reducung the escaping tendency of the solute particles into vapour there by lowering its vapour pressure
