why does freezing point decrease on lowering of vapour pressure?
yeah thats the question, on addition of non volatile solvent why does this happen?

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.freezing point is defined as the temperature where the vapour pressure of the liquid = vapour pressure of the solid
when you put non volatile solute, the vapour pressure of the liquid decreases
Freezing point is that point at which Vp of solid phase of any matter equals its liquid phase nd since vp of solution is lesser than pure solvent, it attains equilibrium with solid phase at a temp lower as compared to freezing point of solvent
wait lemme think this through
ah yes
check this on khanacademy.org made a video on this a few months back, link is in my bio here (bento one)
