To break a chemical bond, particles need to collide with a certain amount of ____?
Harrizon [31]

Explanation:

To break a chemical bond, it is required that particles must have certain amount of energy so that when they can collide with each other due to this energy.

Therefore, there will exist a certain amount of force between the particles which will help in breaking the chemical bond.

This energy due to the motion of particles is known as kinetic energy.

Thus, we can conclude that to break a chemical bond, particles need to collide with a certain amount of kinetic energy.
