Heterogene Katalyse |
|
| Authors: | Mathias Metz Daniel Rohr Reinhard Wagener |
| Abstract: | A technically simple experiment in heterogeneous catalysis useful for student's lab classes is introduced. Ammonia is oxidized via air using manganese iron oxides close to 200 °C. The consumption of ammonia is detected online via an ion‐selective electrode. The determination of the reaction order and the activation energy is demonstrated based on lab course conditions. |
