Question

2. A reaction is studied, the following mechanism is determined, and this reaction coordinate diagram is generated. Please label the intermediates and activated complexes on the diagram: CIO (g)+02 (g) CIO3 (g) Cio, (g) + ClO (g) a,02 (g) + O2 (g) Cl,02 (8)+Br2 (4-2 CIBrO (g) Reaction Progress a. Which step is the rate-determining step? b. What is the role of each of the following molecules? CIO O2 CIBrO CI202 Br2 V. c. What is the rate law for this reaction? (Note: catalysts can be part of a rate law!)

Explanation / Answer

2. Reaction rate study

For the given plot and the reaction

a. The rate determining step would have the highest energy for the transition state, that is the rate-determining step is step 2.

b. role of the following molecules

i. ClO : a reducing agent. It reduces Oxygen in O2 at 0 oxidation state to -2 oxidation state

ii. O2 : Is a oxidant. It oxidized Cl at +2 oxidation state in ClO to +6 oxidation state in ClO3

iii. ClBrO : Is the end product

iv : Cl2O2 : Is a oxidizing agent. It oxidizes Br in 0 oxidation state in Br2 to +1 oxidation state in ClBrO

c. rate law for the reaction,

rate = k[ClO3][ClO]

with k being the rate constant

v. Br2 :
