NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document. When a mixture of ozone and nitrogen pentoxide is allowed to decompose, the reaction takes place in two stages. During the first stage, while ozone still remains, the ozone immediately oxidizes any nitrogen dioxide formed by the decomposition of nitrogen pentoxide; and the overall result is merely the decomposition of ozone in accordance with the reactions [...]. The second stage of the reaction, after the ozone is all used up, is then the well known first order decomposition of the nitrogen pentoxide according to the reaction [...]. The start of this latter reaction is indicated by a break in the decomposition curve, the slope of the total pressure-time curve being greater at the beginning of the nitrogen pentoxide decomposition than at the end of the ozone decomposition; and also by the formation of brown NO2, which can be readily observed in case the initial pressure of the nitrogen pentoxide is high, 15 mm. or more. The purpose of this research was to study the ozone decomposition, especially the decomposition in the neighborhood of the point of inflection of the total reaction curve and possibly get a further insight into the mechanism of the N2O5 decomposition.
