Physical Description

Abstract: The rate constant for the reaction CO + H2O2 → HOCO + OH (R1) at 713 K is determined based on the batch reactor experiments of Baldwin et al. [R.R. Baldwin, R.W. Walker, S.J. Webster, Combust. Flame 15 (1970) 167] on decomposition of H2O2H2O2 sensitized by CO. The value, k1 (713 K) = 8.1 x 10(2) cm3 mol-1 s-1, is consistent with spin-unrestricted density functional theory. Extrapolation to a wider temperature range through ab initio calculations yields the rate constant k1 = 3.6 x 10(4) T(2.5) exp(-14425[K]/T) cm3 mol-1 s-1. The reaction is probably of minor importance in combustion. The present analysis reconciles the batch reactor data of Baldwin et al. with recent high-level theoretical work on the CO + HO2 reaction.
