Abstract: | The decomposition rates of hydrogen iodide over platinum supported γ-alumina were measured in the range from 480 to 700 K by the use of a flow method. It was found that Pt/γ-alumina catalyst was effective for the decomposition of hydrogen iodide. According to the Langmuir-Hinshelwood model, an overall rate equation was obtained on the basis of the mechanism where the rate-determining step was a surface reaction. Experimental data were well correlated with the rate equation. |
