For an exothermic chemical process occurring in two steps as as a+b x (slow)i) the progress of the reaction can be best described by

Correct answer is (B). As it's exothermic Reaction & will require energy to overcome the Transition barrier. As A+ B - X is a slow Reaction thus Rate Determining step. Now as the ...

The reaction occurring in two steps has two activation energy peaks. The first step being slow needs more activation energy. The second step being fast, needs less activation energ...
