Methods of Testing for Mass Transfer Limitations

How is a carrier particle with biocatalytic activity tested for potential mass transfer limitations  

After the absence of film diffusion effects has been verified and if the reaction order n is known, the expression for the rate equation r = r) kcat[E][S]buik/KM (first-order reaction assumed) can be inserted into the definition for 7j and the unknown rate constant k can be eliminated (Weisz, 1954) [Eq. (5.66)]. 

If pore diffusion does not play an important role 7j - 1, and thus / 1 and thence also Eq. (5.67) holds.
