Reaction rate
Reaction rate. Steel wool is made of very thin bundled steel filaments (25 micron thickness used here). A wad of steel wool is ignited by a Bunsen burner and starts to burn. 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 a stream of pure oxygen is additionally supplied through a nozzle, the reaction rate increases dramatically along the stream of oxygen, where its concentration is higher than in the surrounding air.
