Electron pulse radiolysis a t -298'K of 2 atm Hz containing 5 torr 0 2 produces HOz free radical whose disappearance by reaction (I), HOz + HOz -HzOz + 0 2 , is monitored by kinetic spectrophotometry a t 230.5 nm. Using a literature value for the HOz absorption cross section, the values k = 2.5 X cm

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
