Absolute rate coefficients for the reactions of the hydroxyl radical with ethane (kl, 297-800 K) and propane (kz, 297-690 K) were measured using the flash photolysis-resonance fluorescence technique. The rate coefficient data were fit by the following temperature-dependent expressions, in units of c

β¦ Synopsis
The reactions of ozone with propane and ethane were studied in the temperature range 0" to 60Β°C in thermostated infra-red gas cells. The major products of the ozone-propane reaction were found to be carbon dioxide, water vapour, acetone, formic acid and methanol. Major products of the ozone-ethane reaction included all the above with the exception of acetone. In the bresence of added oxvtren the activation enerEv for the ozone-brobane reaction, calculated ok the basis of the ix>ression -d [03]/dt=g[&] [C~HB] was'fozhzd to be 14.6 kcal mole-l. The fire-exponential term was 2.12X lOa 1. mole-l set-1. the numbed of moles of ozone conszlmed. The low values obtained for the activation energy are taken to indicate that the initiating agent in the reactions is the ozone molecule.
