The reaction shown by the second diagram is more exothermic. There is a greater difference in energy between the reactants and products. The green arrow is longer.
The oxidation of the iron is an exothermic process. Heat packs that contain supersaturated sodium acetate: These are reusable, the packs are boiled to dissolve sodium acetate. Inside is a metal ...
In an endothermic reaction, more energy goes into breaking the bonds of the reactants than is released when the bonds in the products are formed. In this reaction, the temperature goes up so it is ...
