Rate of Dissolution at Equilibrium
At equilibrium, the rate of dissolution of a solid solute in a volatile liquid solvent is equal to the rate of crystallization. This means that the amount of solute dissolving in the solvent is the same as the amount of solute crystallizing out of the solvent.
Explanation
When a solid solute is added to a volatile liquid solvent, the solute particles start to dissolve in the solvent. As more solute particles dissolve, the concentration of the solute in the solvent increases, leading to a higher rate of crystallization. At the same time, as solute particles crystallize out of the solution, the concentration of the solute in the solvent decreases, leading to a lower rate of dissolution.
As the dissolution and crystallization rates reach equilibrium, the amount of solute dissolving is balanced by the amount of solute crystallizing out of the solution. This dynamic equilibrium is maintained as long as the conditions remain constant.
Therefore, at equilibrium, the rate of dissolution of a solid solute in a volatile liquid solvent is equal to the rate of crystallization. This balance ensures that the concentration of the solute in the solvent remains constant over time.
