  • Kinetics of ammonia decomposition on nickel -

    1983-2-1Two kinetic regimes were observed in the decomposition of NH 3 over nickel wires at temperatures between 750 and 1350K and NH 3 pressures between 5.3 and 133 Pa. At temperatures below 1000K, the decomposition is highly activated (211 ± 20 kJ mol −1), and the rate is independent of NH 3 pressure. Above 1000K aCited by: 56
