the first two reactions are extremely exothermic (the catalyst chamber can reach 800 °c in a matter of milliseconds,) and they produce large volumes of hot gas from a small volume of liquid, making hydrazine a fairly efficient thruster propellant with a vacuum specific impulse of about 220 seconds. reaction 3 is endothermic and so reduces the temperature of the products, but also produces a greater number of molecules. the catalyst structure affects the proportion of the nh that is dissociated in reaction 3; a higher temperature is desirable for rocket thrusters, while more molecules are desirable when the reactions are intended to produce greater quantities of gas.
