Question

Which statement is correct about the rate of a chemical reaction? A. It increases when the concentration of reactants increases. B. It does not depend on the concentration of reactants. C. It increases when the temperature decreases. D. It does not depend on the temperature.

Answer 1

Answer:

It increases when the concentration of reactants increases.

Explanation:

Increasing the concentration of reactants in a reaction increases the amount of reacting molecules or ions which would increase the rate of a chemical reaction. Reaction rate does depend on temperature. Increasing temperature also increases reaction rate because particles move faster with the increased kinetic energy to produce more collisions.
