The kinetics of the reaction of bacterial catalase with H 2 O 2 has been examined. By applying a non‐steady state analysis, the formation curve of the transient intermediate and the kinetics of its formation have been explained. The discussion has been based on the peroxidatic model of catalase action. The rate constants of the reaction are\documentclass{article}\pagestyle{empty}\begin{document}$ \begin{array}{l}{\rm k}_{\rm 1} {\rm = (1}{\rm .55 \pm 0}{\rm .10) } \times {\rm 10}^{\rm 7} {\rm M}^{ - {\rm 1}} {\rm s}^{ - {\rm 1}} \\ {\rm k}_{\rm 1} {\rm = (3}{\rm .26 \pm 0}{\rm .20) } \times \,1{\rm 0}^{\rm 7} {\rm M}^{ - {\rm 1}} {\rm s}^{ - 1} \\\end{array} $\end{document}The (corrected) spectrum of the transient intermediate has been evaluated.
