摘要: The kinetics of sulfur transfer from H2S to cuprous sulfide (digenite) at 500°C has been established by the resistance relaxation technique. measurements have carried out van der Pauw method, which uses a four probe configuration. rate forward reaction decreases with increase in activity (rate ∞a s −0.55 ) while backward is found be nearly independent activity. Based on these results, limiting step for digenite shown be: (g) + 2e− = S2−(ad) H2(g).
