Increasing the concentration will increase the reaction rate.

True
False

True

True.

Explanation:
Increasing the concentration of reactants generally increases the reaction rate. This is because a higher concentration means more reactant particles are present in the same volume, leading to a higher frequency of collisions between particles. As a result, the likelihood of successful collisions with enough energy to overcome the activation energy barrier is increased, leading to a faster reaction rate.

True. Increasing the concentration of reactants typically increases the reaction rate. This is because a higher concentration means more particles are present in a given volume, leading to more frequent collisions between the reactant particles and an increased likelihood of successful collisions, which results in a faster reaction rate.
