Why are there energy changes in chemical reactions?

WebYou can very easily tell if a reaction is endothermic or exothermic by looking at the potential energy diagram. If the potential energy of the products is less than that of the reactants, the reaction is exothermic. (You can remember the mnemonic device exo low.Exothermic PE diagrams end lower than they start.) WebExplanation: So, the diagram in the option 1 is the correct choice. View the full answer. Step 2/3. Step 3/3. Final answer. Transcribed image text: A chemical reaction is endothermic and has an activation energy that is twice the value of the enthalpy of the reaction. Identify a diagram depicting the energy of t progresses. WebMar 22, 2024 · Difference between Endothermic and Exothermic Reactions. The words ‘Endo’ and ‘Exo,’ which mean ‘within’ and ‘out,’ respectively, have Greek roots. The major difference between endothermic and exothermic reactions, as their names suggest, is that the former absorbs heat from the surroundings while the latter releases it. legal help in ohio
