The following initial rate data are for the reaction of nitrogen monoxide with ozone at 25 ^oC:

NO + O3 --> NO2 +O2

Experiment	[NO]0, M	[O3]0, M	Initial Rate, Mxs^-1
1	0.143	0.0439	0.620
2	0.143	0.0878	1.24
3	0.286	0.0439	1.24
4	0.286	0.0878	2.48

Complete the rate law for this reaction in the box below.

Use the form k[A]^m[B]^n , where '1' is understood for m or n and concentrations taken to the zero power do not appear. Don't enter 1 for m or n .
