A theoretical model is proposed to extract rate constants of second-order chemical reactions down to the millisecond time scale from the observation of reactiondiffusion processes in a microchannel. We validate this theoretical approach by examining an appropriate model reaction. The measured rate constant is in excellent agreement with this obtained from nuclear magnetic resonance experiments.
