What condition must be met for a solution to freeze?
Options
- AIts vapour pressure must be higher than the vapour pressure of the pure solid solvent.
- BIts vapour pressure must be lower than the vapour pressure of the pure solid solvent.
- CIts vapour pressure must be equal to the vapour pressure of the pure solid solvent.
- DIts vapour pressure must be higher than the atmospheric pressure.
Correct answer
C. Its vapour pressure must be equal to the vapour pressure of the pure solid solvent.
Step-by-step solution
A solution will freeze when its vapour pressure equals the vapour pressure of the pure solid solvent.
