WebIn effect, the electron has been transferred from the iron to the oxygen. This combined redox reaction is possible if there is a surplus of Fe+2 and oxygen simultaneously. The iron serves as the reducing agent, and is itself oxidized. The oxygen serves as the oxidizing agent and is itself reduced. WebThe reaction is much faster than for uncomplexed Fe2+ and a rate constant, k = 1 x 10(4) M(-1) s(-1) is deduced for Fe(II)(ox). The reaction of Fe(II) oxalate with dioxygen is strongly pH dependent in a manner which indicates that the reactive species is Fe(II)(ox)2(2-), for which an apparent second order rate constant, k = 3.6 M(-1) s(-1), is ...
