Explanation of Solution

Introduction:

An exothermic reaction is a chemical reaction that release energy in the form of heat. The example of exothermic reaction is burning of wood and explosive of dynamite.

In exothermic reaction, the free energy of the product is less than the free energy of the reactant. The difference of this free energy is released in the form of heat, light, sound and electricity.

Conclusion:

Hence, free energy is the source.
