INTRODUCTION. All reactions require energy to break bonds in the reactants, and all reactions give off energy when new bonds form to make products. The difference in energy required to break the bonds and to make the new bonds can tell you whether the reaction is endothermic or exothermic. . Agenda. :. Warm up.
