In an electrochemical reactor, continuous flow type and tubular shape, developed in my laboratory, it appears that the conversion depends exponentially on the concentration supplied. Can anyone offer an explanation?
Could you be more specific on supstrate/if it`s enzymatic, or reaction type if it`s chemical reaction?
It is an heterogeneous electronic transference, the oxidation of ferrocyanide over the inner surface of an SS medical needle acting as electrode
Without more information, I would say that your conversion is limited by rate. As a result, at higher concentrations where the reaction is faster you obtain higher conversions for a given flow rate, since you are in continuous flow you concentration remains nearly constant. Have you tried decreasing the flow rate at lower concentrations?
For a given flow rate and concentrations higher enough, the conversion slowly diminished when the concentration increases (I think that conversion is limited by ET rate), but for lower concentrations the conversion falls strongly (perhaps the conversion is limited by concentration?). I try to do further experiments at slow flow rates but I haven't the results yet.
