Question

When the concentration of the reactants increases, the rate of reaction will.

• A. decrease
• B. increase
• C. remains constant

Answer 1

The correct option is B increase

• An increase in the concentration of the reacting substances results in an increase in the rate of the reaction.
• When more molecules are present in a smaller volume, the chances of collision are greater.
• Since the rate of the reaction is dependent on the number of collisions occuring between the reactants, the rate increases as the concentration increases.
