Kinetics of Ion‐Molecule Reactions in Gases: Equilibrium and Nonequilibrium Theory with Applications

Abstract

AbstractFor calculating rate coefficients of ion‐molecule reactions the formalism of kinetic theory of weakly ionized diluted gaseous plasma is used. – Equilibrium rate coefficients of proton transfer reactions between ions and polar molecules show a weakly temperature‐dependent Arrhenius‐like behaviour. – Analogous nonequilibrium rate coefficients give a reaction‐induced kinetic isotope effect in reactions between small ions (H−, D−) with polar molecules (CH3CHO) in heavy carrier gases (xenon).
