Definition

Interaction between chemical (or biochemical) reaction kinetics and molecular diffusion such that diffusion acts to redistribute species while reactions create or deplete them; the interplay can produce spatial concentration gradients, moving reaction fronts, and patterning or instabilities when reaction nonlinearities couple with finite diffusion rates.
