Abstracthas been investigated at pressures of 1·10‐6 and 2·10‐6 torr and temp. between 500 and 1250 K. Above 750 K, the reaction rate of the catalytic NH3 decomposition approaches first order in NH3 pressure and the apparent activation energy is 5.0 kcal mol‐1. A kinetic isotope effect is observed at these high temp. and the activation energy for ND3 is determined to be 6.6 kcal mol‐1. The apparent activation energy is associated with the difference in activation energies between that of the cleavage of a N‐H (N‐D) bond in chemisorbed NH3 and that of the desorption of molecularly chemisorbed NH3.
