Question

At equilibrium the rate of dissolution of a solid solute in a volatile liquid solvent is :

• A. less than the rate of crystallization
• B. greater than the rate of cyrstallization
• C. equal to the rate of cystallization
• D. zero

Answer 1

Answer: (C)

equal to the rate of cystallization

Crystallization is the process of formation of solid crystals precipitating from a solution, melt or more rarely deposited directly from a gas.

In Unsaturated solution, rate of dissolution of solute in a volatile liquid solvent is greater than rate of crystallisation.

In supersaturated solution, rate of dissolution of solute in a volatile liquid solvent is less than rate of crystallisation.

At equilibrium, rate of dissolution of solute in a volatile liquid solvent is equal to rate of crystallisation.
