Endothermic and Exothermic Reactions and their Differences

WebAn endothermic reaction views it as a reactant, while an exothermic reaction views it as a product. So increasing the temperature in means adding extra energy to that enthalpy energy. In effect it adds additional reactant or product similar to increasing the concentration of chemical species. WebBoth endothermic and exothermic organisms have evolved specific adaptations to help them survive in their respective environments. Endothermic animals have a higher metabolic rate, which allows them to generate more heat and maintain a constant body temperature.
