Answer 2

Answer;

Collision theory

Explanation;

-Activation energy is the minimum amount of energy that is required by the reactants to start a chemical reactions. According to collision theory atoms or molecules of reactants must collide with sufficient energy, known as activation energy, for chemical bonds to break and thus initiating a chemical reaction.

-Furthermore, according to collision theory when molecules  of reactants collide, the chemical bonds between their atoms are broken, and then new bonds are formed to make new molecules.
