The decomposition of nitrous oxide on pure and doped cupric oxide with ions of lower and higher valency was studied in detail. The heat treatment of cupric oxide between 550-800 °C resulted in about 14 kcal increase of the activation energy. The building-in of ions of higher valency increased to a marked extent the activation energy, whereas the incorporation of lower valency ions decreased the activation energy to a lesser extent. According to the present conductivity measurements, cupric oxide-in contrast with earlier observations-proved to be a defect conductor. The kinetics of the decomposition of N2O can be interpreted on the basis of this type of conductivity.
