Answer:
C. Thermal energy. Potential energy is stored energy when. it's released it becomes kinetic energy. Activation isn't a type of energy.
The energy change in the chemical reaction has been thermal energy. Thus, option C is correct.
The chemical reaction has been given as the reaction in which the reactants have been converted into products. The products have varying chemical structure and properties than reactants.
The bond formation and bond breaking has been mediated with the absorption or release of the heat from the bonds. The heat has been able to change the surrounding environment of the chemical reaction.
Heat has been a form of thermal energy. Thus, thermal energy change in the chemical reaction has been taken in bond breaking and forming. Hence, option C is correct.
