This chapter explains the sensitization and inhibition of the hydrogen–oxygen reaction by additives and the role of NO in the explosive reaction of hydrogen and oxygen. The inhibiting effect of NO2 implies that NO2 undergoes a reaction, which destroys H atoms, and in this way counteracts the ...
WE have made a preliminary survey of the principal respects in which the reaction of deuterium with oxygen differs from that of ordinary hydrogen. The deuterium was prepared by the nearly quantitative decomposition of 97 per cent deuterium oxide by repeated passage over pure iron. The reaction ...
The retardation must be due either to the destruction by a surface decomposition of something which catalyses the principal reaction, or to the interruption of reaction chains, in a manner which has already been discussed. The homogeneous reaction between hydrogen and oxygen is interesting if only ...
