Abstract

Abstract: A new, simple method for the determination of the rate constant, k_f, and the activation energy, E_α, 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 k_f for the system of Mo(Ⅵ)-H₂SO₄-NH₄NO₃ was determined. The E_α for these studied systems were reported.

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