Different possible forms of the kinetic equation for the reaction between PdCl42-and olefin in aqueous solution were analyzed. It was concluded that over a wide range of temperature, ionic strength, and concentrations of PdCl42-, Cl-, and H30+ the kinetics of olefin oxidation are described by a two-term equation (including a quadratic term in [PdCl42-]) rather than by a one-term equation, the latter being valid only for low Pd(II) concentration. The validity of the two-term equation extends over a wide range of variation of numerical values of the equilibrium constants of the -complex formation used in calculations of the reaction rates. A comparison of the rates of ethylene oxidation in solutions of identical initial composition observed by the authors and by Henry leads to the conclusion that diffusion limitation seems to be appreciable in Henry's studies of the gaseous ethylene uptake by
