✦ Synopsis

The kinetics of the SOI to SO, oxidation reaction at electrocatalytically active Pt and V,O, electrodes have been investigated by means of the solid state electrochemical technique in the 45%550°C temperature range. The results, reported in terms of theconversion of SO, to SO, are compared with that calculated from the equilibrium constant of the reaction SO,@ + )0,(g) * SO,@)

and show that the electrcchtically generated oxygen behaves as an "active" oxygen and that, at the higher current densities, the electrolyte presumably is the catalytically active surface.
