Rate in hydrogen

A more complicated problem is that of suppression of the effect of internal diffusion on the reaction rate. In hydrogenation processes the concentration of an unsaturated compound in the liquid state is usually higher by several orders of magnitude than that of hydrogen. If the concentration gradient of the substrate inside the catalyst grain due to diffusion is not too high, the internal diffusion of the substrate cannot have any essential influence on the...

The recombination rates in hydrogen flames were also examined by Halstead and Jenkins in a careful and extensive series of studies. They used not only nitrogen but also helium, argon, steam and carbon dioxide as diluent. Only a limited range of temperature was covered...
