FREE Expert Solution

We're being asked to determine the rate law for the proposed mechanism.

NO + O3 → NO3 + O     Fast

NO3 + O → NO2 + O2   Slow


When a reaction mechanism is given, the rate law can be determined using the slow step in the reaction mechanism.

Problem Details

The proposed mechanism for a reaction is

NO + O3 => NO3 + O     Fast

NO3 + O => NO2 + O2   Slow

Which of the following would be a rate law for the reaction?

a. rate = k [NO][O3]

b. rate = k [NO] [O] [NO] [O3]

c. rate = k [NO3] [O] 

d. rate = k [NO]

e. rate = k [NO] [NO3]
