Construct simple enthalpy level diagrams showing the enthalpy change. 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. . Oxidation Reactions. Exothermic vs Endothermic. Exothermic. Endothermic. A chemical reaction that gives off energy.. The reactants have more energy than is needed to form the products so they release it.. Agenda. :. Warm up. Intro to the world of chemistry – . Episode 13 – the driving forces of reactions . Notes – Energy changes and Reaction rates . Complete WS: Heat and endothermic / exothermic reactions . By . DR T. .

You might think of chemical reactions as occurring exclusively in laboratories, but in reality, they occur in the world around us and in our own bodies every day. . Success is the result of preparation, hard work and learning from failure. Describe the difference between an exothermic & . an endothermic . reaction.
