Before revision:  We quantify transport effects on such multiple-component reactions, which result in a nonlinear set of integrodifferential equations for the reacting species concentrations. In physically relevant parameter regimes, these integrodifferential equations further reduce to a nonlinear set of ordinary differential equations, which may be used to estimate rate constants from biosensor data.
