11. Lime hydration is an exothermic reaction that can be performed with water or steam. 12. That tends to be an exothermic reaction . 13. This differs from a exothermic reaction or a endothermic reaction where the entropy is not included. 14. In an exothermic reaction , the temperature in the sample cell increases upon addition of ligand. 15. Metals which can form intermetallic compounds by an exothermic reaction are another class of candidate materials. 16. Kim et al used a metal nitrate solution with an oxidizer to create an exothermic reaction . 17. It has to be heated very gradually to prevent explosion due to its strong exothermic reaction . 18. The VCS mode is typically used for weakly exothermic reactions that require preheating prior to ignition. 19. In designing a circulating fluidized bed, with constant temperature distribution for either endothermic or exothermic reactions . 20. Although, technically speaking, exothermic reactions indicate that the reactants are metastable compared to the products.
