Abstract: Lactic acid generates chemical oscillations in the Belousov—Zhabotinskii reaction if the solution is bubbled through with nitrogen. The frequency of oscillations / of heterogeneous oscillating reactions depends on temperature. The linear relationship between In {/} and 1/T was used for determining activation energies of the oscillating reactions of the Belousov—Zhabotinskii type with substrates which cannot undergo bromination, i.e. lactic, tartaric, and oxalic acid at equal initial concentrations of reactants.
