The Heterogeneous Decomposition of Hydrazine. Part 4. The Kinetics of the Decomposition of Liquid Hydrazine on a Supported Rhodium Catalyst

Abstract

The kinetics of the decomposition of liquid hydrazine on a supported rhodium catalyst exhibit a change from half order for low concentration of hydrazine to zero order for high concentrations of hydrazine. The reaction follows the stoichiometry 2N2H4 to N2 + H2 +2NH3. The observed kinetics have been explained by deriving the rate equations from the Langmuir adsorption isotherm on the assumption that the hydrazine molecules are dissociatively adsorbed as NH2 radicals. A mechanism is postualted which involves a Langmuir- Rideal type of reaction between adsorbed radicals and a liquid phase hydrazine molecule.
