Abstract
Recent determination of the standard enthalpy of formation of the ammonium azide Δf H O (NH Δ N 3,c) and the assignment of the viscosity B-coefficient for the azide anion, B(N −3 ,aq), in aqueous solution enable us to estimate the standard enthalpy of formation of the gaseous azide anion, Δf H O (N −,g3 , — a thermochemical magnitude in some dispute — to be 192 kJ-mol−1.
