Energy Diagrams. Exothermic versus Endothermic Reactions. Exothermic Reactions Reactions that release heat are termed exothermic. In a exothermic reaction the resulting products have more or more stable bonds than the reactants. The ΔH of reaction for an exothermic reaction is less than zero (ΔH rxn < 0). Exothermic Diagram. Energy released in bond making. Activation Energy. Energy used in bond. breaking. Exothermic - More energy is released when the products where formed than energy was used to break bonds in the reactants. Therefore, a net release of energy.
1. Identify the general shape of the energy diagram Energy should conserve for any chemical reaction. The reaction in question is exothermic (releases heat) hence its products shall have chemical potential energies lower than that of its reactants- some of the potential energies have been converted to thermal energy during the reaction process. Energy level diagram for an exothermic chemical reaction without showing the activation energy.It could also be seen as quite exothermic with a highly unlikely zero activation energy, but reactions between two ions of opposite charge usually has a very low activation energy. Could usually . has a very low activation energy. The reaction shown by the second diagram is more exothermic. There is a greater difference in energy between the reactants and products.

Endothermic Reaction Energy Level Diagram: Endothermic reactions are depicted in a basic energy level diagram below. The activation energy is the amount of energy that must be delivered to the reactants for them to break through the energy barrier and react. In an endothermic reaction, the result has higher potential energy than the reactants.

Exothermic And Endothermic Processes Introduction To Chemistry
This is an exothermic reaction (heat is given off) and should be favorable from an energy standpoint. The energy difference between A and B is E in the diagram. However some energy is required for A to convert to B. This energy is called the activation energy or E act. Sometimes this is also called the activation barrier.
