Popis:	Accelerating rate calorimetry has been used to study the kinetics of the titanium thermal decomposition of liquid and vapor hydrazine over the temperature range 475–590 K. In a titanium reaction vessel, hydrazine decomposes exothermically to ammonia, nitrogen and trace amounts of hydrogen. While both liquid and vapor hydrazine are present the reaction has an apparent zero-order activation energy of 98.3±1.7 kJ mol −1 . Cessation of the hydrazine liquid-vapor equilibrium is noted as a dislocation of the log (temperature rate) -inverse temperature relationship and an inflection point on the pressure rate profile. Procedures for the analysis of chemical reaction rate data from the accelerating rate calorimeter and for modeling adiabatic reaction kinetics are presented. Comparison with the experimental results for hydrazine decomposition is made.
