Abstract
Sustained oscillations of the reaction rate were observed during the oxidation of hydrogen on a palladium wire whose temperature was maintained constant by a constant temperature anemometer. This oscillatory behavior was observed only within a region of operating conditions under which the activity of the wire responded very slowly to sudden changes in the limiting reactant's concentration. The slow activity changes and oscillations are probably caused by stow surface oxidation and reduction. The oscillatory states are independent of the linear gas velocity for sufficiently high velocities, indicating that they are not caused by the coupling between chemical and transport rate processes.
