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.
