Answer:
The correct answer is option A.
Step-by-step explanation:
Activation energy is defined as amount of energy given to a chemical system with which results in chemical reaction.Or minimum amount of energy required by the reactants to undergo a chemical reaction.
Activation complex is a state in a chemical reaction which attained at very high temperature. It is an intermediate state between reactant and product.
The kinetic energy of reactants is the energy due to motion of the reactant molecules.
The potential energy of products is the chemical energy possessed in the bonds of the product.
