N2  - Ammonia is oxidized by nitrous oxide smoothly and homogeneously at temperatures between 658 and 730° and total pressures up to 250 mm. The products of reaction, nitrogen, water, and hydrazine are accounted for by a free-radical mechanism initiated by oxygen atoms which result from the thermal decomposition of nitrous oxide. Ammonia labelled with the 15N-isotope was used to distinguish between the nitrogen formed from the nitrous oxide and that from the ammonia.   The kinetics follow an empirical rate equation,               Rate = k'[N2O]1.56 + k&quot;[N2O]0.61[NH3]. This is of a form which shows the importance of the ammonia molecule participating in the activation of nitrous oxide through bimolecular collision. Assigning a collisional efficiency of unity for like N2O-N2O collisions, the efficiency of ammonia in the process              NH3 + N2O &#8594; NH3 + N2O* is determined as 0.85.
