Question

Why does increasing the concentration of reactants increase the reaction rate? A. Some of the reactants are likely to act as catalysts. B. The temperature increases with higher concentrations. C. Collisions of the right energy are more likely. D. Increasing the concentration changes the rate constant

Answer 1

C. Collisions of the right energy are more likely.

Step-by-step explanation:

By increasing the concentration of reactants, a higher number of reacting molecules or ions are present in the reaction. This increases the chances of collisions occurring to increase the reaction rate.
