Thermal Dissociation Rate of Hydrogen

摘要

The thermal dissociation rate of hydrogen in xenonhyphen;hydrogen mixtures has been studied with shockhyphen;wave techniques over the temperature range 3000ndash;4500deg;K. The observed density profiles were consistent with the rate constant expressions:H2plus;Xeequals;Xeplus;2Hkequals;1.8times;1017Tminus;12explpar;minus;Dsol;RTrpar;cm3moleminus;1secminus;1H2plus;H2equals;H2plus;2Hkequals;1.8times;1020Tminus;32explpar;minus;Dsol;RTrpar;cm3moleminus;1secminus;1H2plus;Hequals;3Hkequals;1.2times;1018Tminus;12explpar;minus;Dsol;RTrpar;cm3moleminus;1secminus;1.
