The following shows the potential energy diagram of the reaction: HA HB-Hi HA-HB H Match the following arrangement of H atoms (a) (d) with the correct target on the potential energy diagram, and indicate the reaction path. Potential energy (a) Ha H. -HG (b) HA He He (c) Completely dissociated state HA H (d) Activated complex l 1. Which of the reaction profiles in the following figure represents the effect of a catalyst on the Co 9 x ES O Type here to search 9:39 PM 5/31/2017Explanation / Answer
Step-1 Reaction
HA+HB-HC-----> HA-HB+HC
Step-2 Matching the correceted Pair
Answer is (d) Activated Complex HA....HB....HC
Step-3 Understanding what is activated Complex
An Activated complex is combination of reacting molecules,that are intermidiate between reactant and products.Some bonds are weakend and the new bonds are formed. activated complex cannot be isolated. It break down either to give reactant and products depending on the experimental conditions. Thus the stable molecules before been converted into products, must passed through an unstable, high energy intermidiate species.This highly reactive transient species is known as activated complex.
Step-4 Reaction Path
Labelling the atoms A, Band C. The reaction can be represented as,
HA + HB - HC ----->[HA....HB....HC] Activated Complex ------> HA - HB +HC
