Di-nitrogen penta-oxide reacts with nitrogen oxide to form nitrogen di-oxide. This reaction is described by the following equation:

N2O5 + NO

3 NO2

What is the experimental determined rate law which is consistent with the following mechanism that proposed for this reaction:

step 1:

N2O5

NO2 + NO3

slow

step 2:

NO + NO3

2 NO2

fast

What is the rate law experimentally determined for this reaction which is consistent with this mechanism?

Rate = k .	[N2O5]		[NO]		[NO2]		[NO3]
