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