Deduction of Low Density Limit to Rate Coefficients for Tertiary Association of Ions and Polar Molecules from Measurements

摘要

The low density limit ko to the rate coefficient for tertiary association of ions and polar molecules is related through a double integral to an entity z1 or z2 that involves only the temperature, the reduced mass of the colliding pair, the polarizability and dipole moment of the neutral, and k(exp)M, where k(exp) is the measured rate coefficient at ambient gas density M. The results are parameterized so that ko may easily be found from laboratory data (irrespective of whether or not third order kinetics prevail).
