V. Lissianski et al., HIGH-TEMPERATURE MEASUREMENTS OF THE RATE COEFFICIENT OF THE H-]CO+OHREACTION(CO2), Chemical physics letters, 240(1-3), 1995, pp. 57-62
The rate coefficient of the reaction H + CO2 --> CO + OH (1) was measu
red using OH concentration measurements in shock-heated N2O-H-2-CO2 mi
xtures and through the inhibiting effect of CO2 on methane ignition. F
or 2170 < T < 3150 K the two methods give concordant results and imply
k(1) = 2.0 X 10(14)exp(-13500/T) cm(3) mol(-1) s(-1). Using the equil
ibrium constant together with this and other recent measurements, the
rate coefficient of the reverse reaction was found to be well describe
d by k(-1) = 3.3 X 10(6)T(1.55)exp(402/T) cm(3) mol(-1) s(-1) for the
temperature range 300-3150 K.
