Reaction rate, 1 of 2. Steel wool is made of very thin bundled steel filaments (25 micron thickness used here). A wad of steel wool is ignited and burns slowly in the air. In this combustion reaction a mixture of different iron oxides is produced (FeO, Fe2O3, Fe3O4). The rate of the reaction is limited by the concentration of oxygen (O2) in the air, about 20%. When the steel wool is put into a beaker with pure oxygen, the reaction rate increases dramatically and steel wool burns much brighter. | |
