β¦ Synopsis
The reaction of CzH502 with NO in helium carrier gas at 295 K with [He] = 1.6 X 1017 cm-3 has been studied using a gas flow reactor sampled by a mass spectrometer. Because no parent molecular ion or suitable fragment ion produced by CzH502 could be detected, the reaction was followed by measuring the formation of NO?. In so doing, account had to be taken of the small amount of HOz known to be present in the reaction mixture, which also leads to NO2 on reaction with NO. The rate coefficient for the total reaction of C2H502 with NO was found to be (8.9 f 3.0) X cm3/s, and the path which produces NO2 was found to account for a t least 80% of all CzHs0~.
