Which determines the rate at which a solid solute dissolves in a liquid solvent?

A) The frequency of the collisions between the solute particles.

B) The frequency and energy of the collisions between the solute and solvent particles.

C) The energy of the collisions between the solute particles.

Answer: Option (B) is the correct answer.

Explanation:

According to collision theory it is known that more is the number of collisions between the atoms more is the rate of a reaction.

Therefore, the speed or the frequency and the energy with which atoms are colliding with each other is important in determining the rate of a reaction.

Thus, we can conclude that the rate at which a solid solute dissolves in a liquid solvent is determined by the frequency and energy of the collisions between the solute and solvent particles.

I believe the best answer would be option B) The frequency and energy of the collisions between the solute and solvent particles.
