Question

Why does a lower concentration of dissolved particles increase the reaction rate?A. The dissolved reactant cannot collide with enough energy to react because it is moving slowly when it is dissolved in a solution.B. When there are less dissolved particles in the way, the reactant particles can collide more easily.C. It does not. A high concentration increases reaction rate.D. Concentration is measured inversely. A low concentration indicates a higher portion of dissolved reactant particles.

Answer 1

In this question, we have a situation in which one compounds has a lower concentration and therefore the reaction rate is increased. The best explanation for it is the collision of particles that occur during a chemical reaction, with fewer particles, fewer collisions will be necessary, causing the reaction to occur faster. Therefore letter B is the best option
