D2 pt reaction
WebMar 19, 2002 · Modeling of the endothermic reaction cross sections yields the 0 K bond dissociation energy of D 0 ( Pt + – H )=2.81±0.05 eV (271±5 kJ / mol ). The experimental thermochemistry is consistent with ab initio calculations, performed here and in the literature. WebSep 12, 2016 · The H-2/D-2 exchange reaction was studied on mono-disperse Pt-8 clusters in a mu-reactor. The chemical activity was studied at temperatures varying from room temperature to 180 degrees C using mass spectrometry. It was found that minute amounts of O-2 in the gas stream increased the chemical activity significantly.
