One mechanism for the destruction of ozone in the upper atmosphere is
Os(9) + NO(g) → NO₂(g) + O₂(g) Slow
Fast
NO₂(g) + O(9)→ NO(g) + O₂(g)
Overall reaction Os(g) +0(g) → 20₂ (9)
a. Which species is a catalyst?
00₁
ONO
O NO₂
00₂
b. Which species is an intermediate?
00₁
ONO
O NO₂
00₂
c. E, for the uncatalyzed reaction
O₂(g) + 0(g) → 20, (9)
is 14.0 kl. E, for the same reaction when catalyzed is11.9 k). What is the ratio of the rate constant for the catalyzed reaction to that for the uncatalyzed
reaction at 25°C? Assume the frequency factor A is the same for each reaction.
