The rate at which ozone, O3 (g), is destroyed in the upper atmosphere is catalyzed by the follwing two step mechanism:   Step 1.           Cl (g)  +   O3 (g)   →   ClO (g)    +   O2 (g)         (slow) Step 2.         ClO (g)  +    O (g)    →    Cl (g)   +   O2 (g)               (fast) Which of the following statements concerning this reaction mechanism is true?

The net reaction                      Cl2 (g)    +   CHCl3 (g)      →    CCl4 (g)    +   HCl2 (g)    Proceeds by the following mechanism Step 1.                             Cl2 (g)   →  2 Cl (g)                                  (slow) Step 2.       Cl (g)  +   CHCl3 (g)   →   HCl (g)    +   CCl3 (g)         (fast) Step 3.         Cl (g)  +    CCl3 (g)    →    CCl4 (g)   +   HCl (g)              (fast) What is the rate law for the rate-determining step?
