Abstract
The rate constant of the gas-phase reaction Fe(a 5 D 4) + CO2 at 1180–2380 K and a total gas density of (7.0–10.0) × 10−6 mol/cm3 behind incident shock waves is k(Fe + CO2) = 1.4 × 1014.0 ± 0.3exp[−(14590 ± 1100)/T] cm3 mol−1 s−1, as determined by resonance atomic absorption photometry. Using thermochemical data available from the literature, the rate constant of the reverse reaction was calculated to be k(Fe + CO) = 9.2 × 1011.0 ± 0.3 (T/1000)0.57exp[−(490 ± 1100)/T] cm3 mol−1 s−1. The results are compared with data reported earlier.
