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.
Chemical reactions are the changes in the reactants to yield the products. The collision theory explains the activation energy and chemical reactions. Thus, option b is correct.
What is collision theory?
Collision theory explains the movement of the particles in the matter that brings about the changes and affects the reaction rate and the product formation.
The theory explains the kinetic energy and collision that causes the reactant to undergo changes with the help of the activation energy, which is the minimum and sufficient energy needed for the atoms or the molecules to react.
The energy needed must be sufficient enough to break the bonds and create new ones in the products in a chemical reaction.
