We both show experimentally and numerically that the time scales separationintroduced by long range activation can induce oscillations and excitability innonequilibrium reaction-diffusion systems that would otherwise only exhibitbistability. Namely, we show that the Chlorite-Tetrathionate reaction, whereautocatalytic species diffuses faster than the substrates, the spatialbistability domain in the nonequilibrium phase diagram is extended withoscillatory and excitability domains. A simple model and a more realistic modelqualitatively account for the observed behavior. The latter model providesquantitative agreement with the experiments.Comment: 19 pages + 9 figure
