RELATIVE RATES OF REACTION OF THE ISOTOPIC SPECIES H2 -HD-D2 WITH HYDROXYL RADICALS IN PERCHLORIC AND ACID SOLUTION

摘要

The effect of temperature on the reaction OH + H2-nH2O + H in aqueous solution has been studied. Substitution of hydrogen deuteride and deuterium for hydrogen increased the apparent activation energy of the reaction. The results suggest that the reaction occurs by H - H bond scission and not by the electron transfer OH + H2 ----» OH- + H2+.
