It is shown that at températures near 800°K and near 1000°K,and for hydrazine molar fractions of the order of unity, 10-2 the entire kinetics reduces to a single, overall reaction. Characteristic times for the chemical relaxation of ail active, intermediate species produced in the décomposition, and for the overall reaction, are obtained. Explicit expressions for the overall reaction rate and stoichiometry are given as functions of température, total molar concentration (or pressure)and hydrazine molar fraction. Approximate, patched expressions can then be obtained for values of température and hydrazine molar fraction between 750 and 1000°K, and 1 and 10-3 respectively. date_type: published date: 1974 place_of_pub: Paris pages: 509 event_title: Colloque International Propiétés de l'Hydrazine et ses Applications Comme Source d'Énergie event_location: Poitiers event_dates: 22-25 Oct 1974 event_type: conference institution: Aeronauticos department: Fisica2 book_title: Propriétés de l'hydrazine et ses applications comme source d'energie referencetext: 1.
