Increasing concentration of solutions affects the rate of reaction by which effect?

Explanation:
Increasing the concentration makes more particles present in the solution, so they collide more often. Each collision between reactant molecules has a chance to lead to a reaction if the energy is high enough and the molecules are oriented properly. With more collisions per second (while temperature stays the same), the number of successful collisions per second rises, so the rate of reaction increases.
