What is exothermic reaction?

An exothermic reaction is a type of reaction in which the energy level of the reactants are higher than that of the product.

It is this discrepancy in the energy levels of both the reactants and products would lead to the generation and release of energy into the surrounding environment.

The enthalpy of exothermic reaction is gotten by the difference between the energy needed to break the bonds of reactants and the energy needed for the formation of products.

Therefore,when the reactants have less enthalpy than the products, then heat energy is given out.
