MCQ
At equilibrium, the rate of dissolution of a solid solute in a volatile liquid solvent is:
- ALess than the rate of crystallisation
- BGreater than the rate of crystallisation
- ✓Equal to the rate of crytallisation
- DZero
✓
Answer
Correct option: C.
Equal to the rate of crytallisation
Crystallization is the process of the formation of solid crystals precipitating from a solution.
In an unsaturated solution, the rate of dissolution of a solute in a volatile liquid solvent is greater than the rate of crystallization.
In a supersaturated solution, the rate of dissolution of a solute in a volatile liquid solvent is less than the rate of crystallization.
At equilibrium, the rate of dissolution of a solute in a volatile liquid solvent is equal to the rate of crystallization.
