The mechanism of the hydrogen-oxygen reaction; the reaction in vessels coated with alkali iodides.

structure and also presumably the chain-breaking efficiency. From the experimental point of view, therefore, the value of E0 as determined in a potassium chloridecoated vessel must be regarded as the more reliable. In conclusion, however, it may be said that the results give general support to the conclusion already reached from the dependence of the function on the con­ centrations of the reacting gases, namely, that the gas phase dissociation of hydrogen molecules is the principal method of chain initiation under the conditions employed.
