摘要： 催化反应在极谱分析中的应用及反应速率常数的测定已有报道[1-7]。通常根据Koutecky[7]公式计算催化反应速率常数,而反应活化能则由不同温度下测定的速率常数,按照Arrhenius公式计算。

Abstract: A new, simple method for the determination of the rate constant, kf, and the activation energy, Eα, of catalytic reaction on the basis of the dependence of catalytic current on the temperature has been developed. The experimental results for several catalytic systems are in a good agreement with those obtained by other methods in the literatures. The new value of kf for the system of Mo(Ⅵ)-H2SO4-NH4NO3 was determined. The Eα for these studied systems were reported.

Key words: Catalytic reaction, Rate constant and activation energy, Temperature effect, Mo(Ⅵ), Ti(Ⅳ)
