%T Overal reaction rate and stoichiometry for thermal decomposition of hydrazine
%A Juan Ramón Sanmartín Losada
%X An asymptotic analysîs of the Eberstein-Glassman kinetic
mechanlsm for the thermal décomposition of hydrazine is carried out. 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.
