The thermal decomposition of ethyl peroxynitrate was studied in a 420 !2 Dural glass reaction chamber in the presence of different initial [NO\*]/ [NO] ratios. From an analysis of the data, the following rate constant ratios k2/kl for the reactions of C2H502 radicals with NO (k,) and NOI (kz) were d

โฆ Synopsis
Tile rate constant for the reaction C2H502 + NO 2 ~ products (10) has been measured directly by flash photolysis and kinetic spectroscopy in the pressure range 44-676 Torr. At room temperature klo = (7.5 ยฑ 0.4) ร 108 ~ mole -1 s -1 so that the rate of formation of the probable primary product, peroxyethyl nitrate (C2HsO2NO2) may be significant in urban atmospheres.
