The reaction of nitrogen monoxide with ozone at 25 °C

Question

The reaction of nitrogen monoxide with ozone at 25 °C

NO + O₃ ---> NO₂ + O₂

is first order in NO and first order in NO .

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, n  ... (don't enter 1) and concentrations taken to the zero power do not appear.

Rate = _________

In an experiment to determine the rate law, the rate constant was determined to be 1.12x10² M^-1s^-1 . Using this value for the rate constant, the rate of the reaction when [NO] =0.171 M and [O₃] = 0.0229 M would be ________ M/s.

Answer 1

You said it was 1st order in NO twice, so I'll assume you meant 1st order in both NO and O₃.

Rate = k[NO][O₃]

Rate = 1.12x10² M^-1s^-1 [0.171 M][0.0229 M)

Rate = 0.439 Ms^-1
