WebThe reaction coordinate diagram for the ozone photolysis reaction is a little different from those above because this is an endothermic reaction. Together, the products O 2 and atomic O, have a higher energy than the reactant O 3 and energy must be added to the system for this reaction. This is primarily due to the very high energy (low ... WebElimination reactions can occur via a variety of mechanisms, one of which is the E2 mechanism, which is a concerted (one-step) reaction. During an E2 mechanism, the base removes the hydrogen while a simultaneous …
