A proposed mechanism for the breakdown of ozone in the atmosphere is as follows:
step 1:** O3+Cl→ClO+O2 (fast)
step 2:** ClO+O→O2+Cl (slow)
(1) What is the molecularity of each step?
(2) Give the overall equation for the reaction.
(3) Deduce the overall rate equation for this reaction.
(4) What is the overall order of the reaction?
(5) What term is used to describe ClO in this reaction?
(6) What name is used to describe the role of Cl in this reaction?
(7) Given that both step 1 and step 2 are exothermic, sketch the energy profile diagram for the reaction.
