Kinetics and Rate Constants of Reactions Leading to Hydration of and in Gaseous Oxygen, Argon, and Helium Containing Traces of Water

Abstract

The rate constants for the forward and reverse components of gas phase reactions: were measured with a pulsed electron beam, time resolved detection high pressure mass spectrometer at 300 °K. O₂, Ar, and He at pressures from 1–7 Torr were used as third gas M. The forward reactions were found to be third order and the reverse reactions second order. Establishment of the equilibria could also be observed.
