The reaction between H 2 and O 2 has been studied in a reflected shock tube apparatus between temperatures of 1662-2097 K and pressures of 400-570 torr with Kr as the diluent gas. O atom atomic resonance absorption spectrometry (ARAS) was used to observe absolute [O] t under conditions of low [H 2 ]
HO2 profiles in the thermal decomposition of H,02 in shock waves over the range 1000-1250 K were analyzed with respect to the reactions HO+HZOz+HOz+H20 (3) and HO+H0r~Hz0+02 (4). Reaction (3) shows a strong up-turn ofthe rate constant at temperatures near 800 K. Over the range 250-1250 K, k, can be
