The reaction of nitric oxide with hydroperoxyl radical and the reaction of hydroxyl radical with hydrogen peroxide were studied in an isothermal flow reactor at pressures around 2 torr with helium as the main carrier gas in an effort to investigate the production of HO/sub 2/ radicals. The reaction of NO with HO/sub 2/ radical led to the production of OH radical and nitrogen dioxide. The reaction of OH with hydrogen peroxide in turn led to the production of HO/sub 2/ radicals and water. Rate constants for each reaction are represented in Arrhenius form. The upper limit for the reaction constant involving the reaction of OH with HO/sub 2/ to give water plus molecular oxygen is also presented.
