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.
