The reactions of ozone were studied in the presence of alkenes [R. Atkinson et al., Int. J. Chem. Kinet., 15(8), 721 (1983)]. The data in Table P7-10 are for one of the alkenes studied, cis-2-butene. The reaction was carried out isother-mally at 297 K. Determine the rate law and the values of the rate law parameters.
Run | Ozone Rate (mol/s-dm3X 107) | Ozone Concentration (mol/dm3) | Butene Concentration (mol/dm3) |
