The production of CO and H atoms from the thermal decomposition of HNCO in shock waves at temperatures between 2,120 and 2,570 K has been measured by resonance absorption. Kinetic modeling of these product formation rates using a recently established mechanism yielded the second-order rate constants for the primary decomposition processes HNCO + Ar {yields} NH + CO + Ar (1) and HNCO + Ar {yields} H + NCO + Ar (2): k{sub 1} = 10{sup 15.41 {plus minus}0.16} exp({minus}39,800 {plus minus} 700/T) cm{sup 3}/(mol {times} s) and k{sub 2} = 10{sup 17.0} exp({minus}56,400/T) cm{sup 3}/(mol {times} s).
