The reaction of nitric oxide with ozone has been studied over a wide range of temperature (212-422 K) by utilizing the discharge flow / mass spectrometric technique.The pseudo-first-order decay of ozone was measured in the presence of a large excess concentration of nitric oxide.The value of the bimolecular rate coefficient at 299 K and the Arrhenius expression determined are k = (1.80 +/- 0.08 ) X 1E-14 cm³ molecule^-1 s^-1 (T = 299 K) and k = (3.16 +/- 0.90) X 1E-12 exp(-(1566 +/- 80)/T) cm³ molecule^-1 s^-1.These results are compared with previous measurements.
