Abstract

The simultaneous influence of temperature and flow rate (k(0)) in the oscillatory regime of the bromate-oxalic acid-acetone-Ce(III) oscillating reaction was investigated. The influence of temperature was evaluated in terms of the oscillatory activation energy (E-omega), which was determined at different flow rates. Increasing k(0), the oscillatory activation energy is decreased, tending to a limit value, E-omega infinity. The sensitivity of E-omega, with k(0) is described by the parameter eta = dE omega/d(1/k(0)). E-omega infinity and eta are global properties of any particular oscillating reaction and describes a correlation between the dynamical behavior and temperature, and should be used when comparing different oscillating reactions.
