With a continuous flow method, flowing is the sole way the sample is mixed. Consequently, there may be imperfect mixing. Thus, the concentration of the adsorptive in the flow chamber may not equal the effluent concentration this is because transport and chemical kinetics phenomena are both occurring simultaneously. 

Nonlinear systems of transport and chemical kinetics analyzed by the generalized Marcelin-de Donder equations consider two competing forward and backward directions of an elementary process. These equations characterize the flow of matter and energy through the energy barrier and contain potentials F = ( /jl/T, 1 IT) in exponential forms... 

Conversely for slow reactions, low rates of mass transport will be required to achieve significant deviations from N fs equalling one. Consequently, it can be appreciated that it is a study of the competition between the rates of mass transport and chemical kinetics that leads to the quantitative determination of electrode reaction mechanisms in hydrodynamic voltammetry. Importantly, for each hydrodynamic technique, there is one assessable convective transport parameter that directly relates to the kinetic time-scale.
