A theoretical model has been proposed to describe the kinetics of oxygen isotopic exchange between gas and oxides with subsurface regions different from the bulk in the rate of oxygen transfer (surface phases, grain boundaries, etc.). Exact solutions valid for an arbitrary ratio between the exchange
