Chemical reactions are characterised by energy changes.It is found that during every reaction ,changes in energy occurs.This is due to the fact that each reacting molecule possesses a certain amount of energy due to the nature of chemical bonds and also does each product molecule.As the bonds of the reacting molecules break and the new bonds of the products form, energy is released or absorbed, depending on whether the reactants have higher or lower energy than the products.Based on that reactions may be exothermic in which energy gets released or endothermic where energy gets absorbed.
