Abstract
Previously measured rates of hydrogenolysis of propylene, toluene, and xylene fit (where θ is 2.3RT kcal mole−1) over an unusually wide range of conditions. In the case of toluene, for example, the range is 107 in rate, 105 in hydrogen pressure, and 500°C in temperature. We propose the mechanism giving . Substitution of values for K1 and k2 gives rate constants and Arrhenius parameters in excellent agreement with all reliable data.
