Default Surface reaction in porous region

CO and O2 flow through a pipe with diameter of 1mm, and the pipe is defined as a porous region. CO oxidation with O2 takes place on the surface of the solid. Can anyone tell me how to define the surface reaction? The reaction rate is power law rate,namely, -r=A*exp(-Ea/R/T)*Cco^(-0.5)*Co2^1.2. Thanks very much.
