Abstract:We investigate the effects of an electric current on the width of a stationary reaction zone in an irreversible A − +B + → C reaction-diffusion process. The ion dynamics of the electrolytes A ≡ (A + , A − ) and B ≡ (B + , B − ) is described by reaction-diffusion equations obeying local electroneutrality, and the stationary state is obtained by employing reservoirs of fixed electrolyte concentrations at the opposite ends of a finite domain. We find that the width of the reaction zone decreases when the current … Show more
