The Temperature Dependence of Reaction Rates from the Standpoint of the Broensted-Christiansen-Scatchard Equation

Abstract

In Section I arguments were presented for the necessity of splitting the log k∞* term in the general kinetic equation into a part which represents the rate constant extrapolated to a standard reference state of temperature, dielectric constant and concentration, and into a part giving the temperature dependence. In Section II the repulsive potential between reactants at close distances was formulated and this potential was then incorporated in the general kinetic equation to give the temperature dependence of the reaction rate constant. In Section III this equation was applied to existing kinetic data and found satisfactory. Also the repulsive forces between reactants calculated from the temperature and dielectric dependence of the reaction rate constants were compared with the intermolecular forces between the molecules of noble gases calculated from the second virial coefficients as evaluated by Fowler.
