- Title
Influence of Nitrogen Dioxide upon the Ignition Temperature of Hydrogen-Oxygen Mixtures.

- Abstract
MR. H. J. SCHUMACHER has proposed (NATURE, July 26, p. 132) an explanation of the explosive action of nitrogen dioxide in hydrogen-oxygen mixtures at temperatures in the neighbourhood of 380° C. The ignition occurs according to Thompson and Hinshelwood between sharply defined limiting pressures of nitrogen dioxide. Schumacher's explanation is based upon the assumed competition of the following two reactions: It is assumed that the oxygen atoms are produced from nitrogen by collisions with 'hot' molecules. Photochemical production of even greater numbers of oxygen atoms1 than could originate in this way has been found unable to cause explosions at temperatures at which nitrogen dioxide in the correct concentrations is effective. On the other hand, the formation of water in the region immediately outside both limiting concentrations falls to negligible values, in contradiction to that which would be expected from the mechanisms (1) and (2).
