Answer: option (B) greater than the energy stored in the bonds of products.Justification:1) In an exothermic reaction, energy is released to the atmosphere as a by-product of the reaction.2) By an energy balance (convervation of energy) is obtained:the Chemical energy of the reactants = the chemical energy of the products + ESince, E >0 (exothermic reaction),the chemical energy of the reactants of the chemical energy of the product > 0 and finally: the chemical energy of reactants > energy of chemical products.Also, you need to know that the chemical energy is a type potential energy is the energy stored in the bonds of compounds.So, the answer is the energy stored in the bonds of the reactants is greater than the energy stored in the bonds of products (option b)
