Iodine monochloride undergoes a substitution reaction with hydrogen gas. The proposed mechanism is shown below: i. \( \mathrm{H}_{2}+\mathrm{ICl} \rightarrow \mathrm{HI}+\mathrm{HCl} \) (slow) ii. \( \mathrm{HI}+\mathrm{ICl} \rightarrow \mathrm{I}_{2}+\mathrm{HCl} \) (fast) a. Which step is the rate limiting step? (D3) b. What is/are the reactive intermediate(s) in this reaction? (D3) c. Using the information in this question, sketch the energy potential diagram for this exothermic reaction. (D2) d. How would you expect your energy potential diagram would change if a catalyst were added? Explain.. You may find it helpful to show part of your answer on your energy potential diagram from part C. (D2) e. If step 2 was the slow step, how would any one of your previous answers change? (D3)
