Abstract

The thermal dissociation rate of hydrogen in xenon‐hydrogen mixtures has been studied with shock‐wave techniques over the temperature range 3000–4500°K. The observed density profiles were consistent with the rate constant expressions:

\begin{matrix} H_{2} + Xe = Xe +2 H & {k=1.8×10}^{17} T^{- \frac{1}{2}} \exp (−D/RT) {cm}^{3} {mole}^{−1} \sec^{−1} \\ H_{2} + H_{2} = H_{2} +2 H & {k=1.8×10}^{20} T^{- \frac{3}{2}} \exp (−D/RT) {cm}^{3} {mole}^{−1} \sec^{−1} \\ H_{2} + H =3 H & {k=1.2×10}^{18} T^{- \frac{1}{2}} \exp (−D/RT) {cm}^{3} {mole}^{−1} \sec^{−1} . \end{matrix}
