Oxidation of metals is generally a slow electrochemical reaction involving many steps. These steps involve
electron transfer reactions. A particular type of oxidation involve overall first order kinetics with respect to fraction of unoxidized metal surface thickness (1ñf) relative to the maximum thickness (T) of oxidized surface, when metal surface is exposed to air for a considerable period of time.
Rate law :
where f = x / T,
x = thickness of the oxide film at time ' t' and T= thickness of the oxide film at t =h
For the oxidation of a particular metal, a graph is shown in the figure.
