repulsive potential-energy surface

Also contains definition of: late-downhill surface

A surface for an exergonic reactionA + BC in which the col corresponds to considerable separation between the products A–B + C . 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.
