The following mechanism has been proposed for the exothermic catalyzed cmplex reaction:
`A + B overset("Fast")rarr IABoverset(k_(1))rarrAB+Ioverset(k_(2))rarrP+A`
If `k_(1)` is much smaller than `k_(2)`, the most suitable qualitative plot of potential energy `(PE)` versus reaction coordinates for the above reaction is
