Answer to Question #318260 in General Chemistry for Angela

Question

One method for the destruction of ozone in the upper athmosphere is:

O3+NO=NO2+O2 (slow)

NO2+O=NO+ O2 (fast)

Overall rxn: O3 +O= 2O2

A. Which species is an intermediate?

B. Which species is a catalyst?

C. Which is the rate determining step?

D. Write the rate law for the reaction

Answer 1

А. NO₂ is the intermediate.

В. NO is acting as a catalyst.

С. O₃+NO=NO₂+O₂ (slow) is the rate-determining step

В. rate = k[O₃][NO
