WebEnergy Level Diagram of an Endothermic Reaction The simple energy level diagram of endothermic and exothermic reactions are illustrated below. The activation energy is the energy that must be provided to the reactants so that … WebA reaction mechanism gives a detailed description of bonds broken and formed in a reaction. A reaction mechanism will include the structures of any reaction intermediates formed in a multistep process. A mechanism shows the relative order in which bonds are broken and formed. homolytic bond cleavage
