Response of Unstable Chemical Systems to External Perturbations.
Abstract
For a system of coupled chemical reactions, with diffusion and in a homogeneous steady state near marginal stability, the response to a periodic external perturbation is derived in a linear analysis and shown to be a resonance phenomena. Responses to perturbations of external variables with small effects on the rate coefficients are amplified at resonance. Suggested applications of the theory are: Study of kinetic parameters and their dependence on external variables; Use of marginally stable systems as analogues of electronic devices; Use of marginally stable systems as sensors and receptors; Out-of-phase external perturbations as stabilization methods; and Double resonance experiments.
