Explanation The energy profile diagram that represents the transition states and the intermediate is shown as, Figure 1 In the given reaction profile diagram, it is clear from the reference of the Figure 1 that A represents the reactant, B represents the intermediate and C represents the product of the reaction. The intermediate is neither a reactant nor a product. It is formed in one elementary reaction and consumed in the next reaction. The steps for the mechanism of this reaction is, A → B B → C Hence, in the reaction, A → C , there is only one intermediate formed that is represented by B . Transition states are always unstable, and they can never be isolated. Hence, in the reaction, A → C , there are two transition states that are represented by the two peaks in the energy profile diagram. The minimum amount of energy required to initiate a chemical reaction is called the activation energy. As the magnitude of activation energy increases, the rate constant decreases because the fraction of molecules that possess the required energy will be less
