✦ Synopsis

Mass spectrometric studies of the ions present in Hz/Oz/N2 flames with potassium and chlorine added have demonstrated that ionization can occur in the forward steps of K + Cl ", K+ f Cl-(II), KC1 t &IS K+ -L Cl-f Vx (IV). where >I k any third body. Variations of [K+] with time in these systems have been measured and establish that the rate coefficients . (in mlmolecule~r S')oftheion-producing stepsare k2 = 5 x 1O-'o T-l'* e~p(--105OO/T) nndJ=+ = 2.2 X 10' T-3-5 X exp(-60 800/T). Coefficients for ion-ionrecombination have been obtained from k2 and ka using the equilibrium constants
