Reverse Reactions and Kinetic Energy Release

Activation Energy of the Reverse Reaction and Kinetic Energy Release... 

Studies of kinetic energy release distributions have implications for the reverse reactions. Notice that on a Type II surface, the association reaction of ground state MB+ and C to form MA+ cannot occur. In contrast, on a Type I potential energy surface the reverse reaction can occur to give the adduct MA+. Unless another exothermic pathway is available to this species, the reaction will be nonproductive. However, it is possible in certain cases to determine that adduct formation did occur by observation of isotopic exchange processes or collisional stabilization at high pressures. 

Another example of a hydrogen elimination process which is both reversible and exhibits a statistical kinetic energy release distribution is the dissociation of the cyclopentadienyl rhodium isopropyl ion, reaction 13(12). In this case the...
