Please show all your work please, thank you! Sorry, this question has many parts. The reaction O3(g)+O(g)→2O2(g), occurs via the following mechanism:Step 1: Cl(g)+ O3(g)→ClO(g)+O2(g); Ea=85 kJ/molStep 2: ClO(g)+ O(g)⇌Cl(g)+O2(g); Ea=10 kJ/mol a. Given the proposed mechanism above, identify any catalysts and any intermediates in this reaction. Be sure to distinguish between the two types of species in your answer. b. Using the proposed mechanism, derive a rate law. *Hint: use the activation energies to determine the slower step. Show all of your work. c. This mechanism was verified by kinetic measurements of the rate of depletion of ozone. How is the rate of change of oxygen gas concentration related to the rate of change of ozone concentration?
