Conclusions
-
1.
The kinetics of the thermal decomposition of solid xenon trioxide was studied at 51–106°. The reaction is described by a first-order equation with activation energy 31.4 kcal/mole and preexponential factor 1014.8 sec−1. The thermal stability of solid XeO3 is low.
-
2.
The kinetic parameters of the decomposition of xenon trioxide in the solid phase and in neutral solution are close (solid xenon trioxide is somewhat more stable). This is evidence that in both cases the particles that undergo decomposition are XeO3 molecules.
