WebAn exothermic reaction is a chemical reaction that releases energy in the form of heat or light. During an exothermic reaction, the reactants have more energy stored in their chemical bonds than the products, so the excess energy is released into the surroundings, resulting in an increase in temperature. In an exothermic reaction, the enthalpy ... WebFigure 7.4 Endothermic Reactions. For an endothermic chemical reaction, energy is absorbed as reactants are converted to products. Exothermic and endothermic reactions can be thought of as having energy as either a product of the reaction or a reactant. Exothermic reactions give off energy, so energy is a product.
