Phase interface
The mass transfer at the phase interface is important, in that it
affects the concentrations of all components in both phases, thereby
influencing all three enzymatic reactions. Experimental results show
that the mass transfer rate of all components is significantly higher
than the reaction rates of all three enzymes. Therefore, the assumption
of instantaneous mass transfer seems reasonable: this leads to a
concentration distribution between the two phases according to the
partition coefficient for each component i as described according to
equation (9).
