The following mechanism has been proposed for the exothermic catalysed complex reaction:
$A + B ⇌_{f a s t}^{s l o w} I A B \overset{k_{1}}{\to} A B + I \overset{k_{2}}{\to} P + A$
If $k_{1}$ is much smaller than $k_{2},$ the most suitable qualitative plot of potential energy (P.E.) versus reaction co-ordinate (R.C.) for the above reaction.

Detailed Solution

$A + B ⇌_{f a s t}^{s l o w} I A B;$ so $E_{a (f)}$ is high and $E_{a (b)}$ is low.

$k_{1} < < k_{2};$ so $E_{a}$ for this step is very high and next step is low and overall reaction is exothermic.
