Answer:

C. A change in concentration results in a change in the rate of a

reaction

Explanation:

We first need to know what is the rate of a reaction;

  • The rate of a reaction refers to the speed at which reactants are converted to products.

Secondly we need to identify several factors that affect the rate of reactions.

  • The rate of reactions depends on a number of factors which include, surface area of reactants, concentration of both reactants and products, temperature, presence of a catalyst, etc.

Thirdly, understand the effect of concentration of reactants and products on the rate of reaction.

  • If we consider the concentration of reactants and products;
  • An increase in the concentration of reactants increases the number of collisions which results to an increase in the rate of reaction.
  • On the other hand, when the concentration of products is increased, the rate of reverse reactions increases for reversible reactions while a decrease in the concentration of reactants favors forward reaction.

Therefore, in our case, we can say that, a change in the concentration of either reactants or products results in a change in the rate of a reaction.
