Q. For an exothermic chemical process occurring in two steps as follows
(i) $A + B \rightarrow X$ (slow)
(ii) $X \rightarrow AB$ (fast)
The progress of reaction can be best described by:

Chemical Kinetics

Solution:

First step is slow (require more activation energy), second step is fast (less activation energy) and overall reaction is exothermic, so product energy level should be less as compared to reactants.
