Question
O3(g) + O(g) → 2 O2(g)
The decomposition of O3(g) in the upper atmosphere is represented by the equation above. The potential energy diagram for the decomposition of O3(g) in the presence and absence of NO(g) is given below.
[VISUAL]
Which of the following mechanisms for the catalyzed reaction is consistent with the equation and diagram above?
A.
2 O3(g) + 2 NO(g) → 4 O2(g) + N2(g) (slow)
B.✓ Correct
O3(g) + NO(g) → NO2(g) + O2(g) (slow)
NO2(g) + O(g) → NO(g) + O2(g) (fast)
C.
NO2(g) + O3(g) → NO(g) + 2 O2(g) (slow)
NO(g) + O(g) → NO2(g) (fast)
D.
NO2(g) + O(g) → NO3(g) (slow)
NO3(g) + O3(g) → NO2(g) + 2 O2(g) (fast)
