A surface for an exergonic reaction A
in which the col corresponds to considerable separation between the products A–B
. The energy barrier in the potential-energy profile is in the later stages of the reaction path. On such a surface most of the energy is released after A–B
is formed. Repulsive surfaces are also called late-downhill surfaces, and the barrier in such a surface is called a Type-II barrier.
