WebJun 14, 2016 · Abstract The H 2 /D 2 exchange reaction was studied on mono-disperse Pt 8 clusters in a μ-reactor. The chemical activity was studied at temperatures varying from room temperature to 180 °C using mass spectrometry. It was found that minute amounts of O 2 in the gas stream increased the chemical activity significantly.

WebQuestion: i) The reaction of cis-2-pentene with D2/Pt is A) regioselective B) stereospecific with an anti addition C) stereospecific with a syn addition D) regioselective and …
WebThe exchange reaction H2+D2→2HD was studied as a function of the angle of incidence (polar and azimuthal) of the beam of reactants on two stepped platinum surfaces, the Pt (S) ‐ [6 (111) × (111)] and Pt (S) ‐ [5 (111) × (111)]. The reaction probability was found to depend markedly on the direction of approach of the reactants to the step structure.
