Energy change diagram exothermic
WebDec 10, 2024 · Energy Diagrams Endothermic and exothermic reactions can be visually represented by energy-level diagrams like the ones in Figure 5.2. 2. In endothermic reactions, the reactants have higher bond energy ( stronger bonds) than the products. Strong bonds have lower potential energy than weak bonds. WebThe 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.
