THE KINETICS OF THE OXIDATION OF FERROUS ION BY HYDROGEN PEROXIDE IN THE PRESENCE OF DISSOLVED HYDROGEN AND CARBON MONOXIDE

Abstract

An expression has been derived for the rate of ferric ion production in the ferrous ion – hydrogen peroxide reaction in aqueous solution containing dissolved hydrogen and oxygen. It involves the relative value of the rate constants for the intermediate reactions[Formula: see text]The effects of side reactions involving the intermediate hydroperoxyl radical are considered. The rate calculated from the derived expression agrees with that measured experimentally (±2%). When carbon monoxide is used instead of hydrogen, the kinetic scheme and rate expression are the same. The agreement between experimental and calculated rates is within ±2%.
