Abstract

A critical comment on Rachwalska's paper titled 'Simple KBrO 3, H 2SO 4 Batch Oscillator' is presented by Vilmos Gáspár and Richard J. Field. The critics say that Rachwalska reported oscillations in redox potential at a Pt electrode in the well-stirred, aqueous, batch system KBrO 3 and H 2SO 4. The origin of these oscillations in homogeneous chemical dynamics is supported by Rachwalska using oscillatory simulations based on the FKN chemistry. The authors say that there are a number of inconsistencies in the description of the simulations based on this mechanism and leading to oscillation. It is stated that the rate constants are taken from Field and Försterling (FF). However, several rate constants are different from the FF values. Most importantly, there are a number of discrepancies between the FKN stoichiometries and the mass-action rate equations displayed by the author.
