The correct statement that explains how concentration of a solution affects the rate of a reaction is:

- When concentration increases, particles collide more often.

Explanation:

1. Concentration refers to the amount of a substance (such as reactants) in a given volume of solution. When the concentration of reactants in a solution increases, there are more reactant particles present per unit volume.

2. In a chemical reaction, for the reaction to occur, reactant particles must collide with sufficient energy and proper orientation. Increasing the concentration of reactants leads to an increased likelihood of reactant particles colliding.

3. The more frequently reactant particles collide, the higher the chances of successful collisions occurring, which can result in an increased rate of reaction.

4. Therefore, when the concentration of a solution increases, particles collide more often, leading to a higher rate of reaction.
