Reactions of Cr atoms with NO, N2O, CO2, NO2, and SO2 molecules

Experimental results on the interaction of Cr atoms with various oxygen-containing molecules (NO, N 2 O, CO 2 , NO 2 , and SO 2 ) at high temperatures (>1000 K) are presented. It is demonstrated that activation barrier for spin-forbidden reactions is higher, all other things being equal. For the reaction of Cr atoms with N 2 O, an interpolated temperature dependence of the rate constant, based on the high-temperature measurements conducted in the present work and the published low-temperature data, is proposed.
