Collisions only result in a reaction if the particles collide with a certain maximum energy called the activation energy of the
Alinara [238K]

Answer: The statement collisions only result in a reaction if the particles collide with a certain maximum energy called the activation energy of the reaction, is false.

Explanation:

Activation energy is the minimum amount of energy required to initiate a chemical reaction.

So, when activation energy for a reaction is lower then molecules with lower energy can also participate in the reaction. As a result, more number of collisions will take place due to which an increase in the rate of reaction will takes place.

When activation energy for a reaction is larger then molecules with higher energy will not be able to participate in the reaction. As a result, less number of collisions will take place due to which a decrease in rate of reaction will occur.

Therefore, we can conclude that the statement collisions only result in a reaction if the particles collide with a certain maximum energy called the activation energy of the reaction, is false.

nevsk [136]
Adaptation is when organisms move to a new place and they settle in. they make a new "home" and find food to adapt to the new environment. Adaption is important because without it organisms will die due to the lack of protection and food.
