Influence of low-frequency vibrations on the chemical reaction rate in the liquid phase for reagent association

A bistable state of a reaction system was theoretically shown to be possible for a multistage chemical reaction in the case of reagent association. The conditions for the bistability origin with a possible substantial change in the rate of reaction product formation were determined. The conditions for the appearance of oscillations of intermediate concentrations and the possibility for the origination of the corresponding acoustic frequencies were studied. The action of external vibrations with the frequency coinciding with that of intrinsic intermediate concentration oscillations can increase the reaction rate of reaction product formation.
