Reactions of Molybdenum Atoms with NO, O2, N2O, and CO2 Molecules behind Shock Waves

Experimental results on the interaction of Mo atoms with various oxygen-containing molecules (NO, O-2, N2O, and CO2) at high temperatures (> 1200 K) are presented, which are in close agreement with measurements at moderate and low temperatures. It is demonstrated that the height of the activation barrier is additionally increased for spin-forbidden reactions and that an increase in the heat of reaction causes an increase in the rate constant for a given type of reaction. For the reactions of Mo atoms with O-2 and N2O, interpolated temperature dependences of the rate constants, based on the high-temperature measurements conducted in the present work and the published low-temperature data, are proposed.
