Temperature-enthalpy plot, methanol

The results of kinetic studies of the oxidation of spinach PCu(I) [H PCu(I), pK = 5.03, is unreactive] by several ferrocenium complexes, in the presence of redox-inactive metal complex inhibitors, support the existence of two surface redox sites, a hydrophobic pocket near His-87 and the hydrophilic region about Tyr-83. Kinetic measurements on the oxidation of spinach PCu(I) by [Fe(CN)6] " at low temperatures (+25 to -35 °C) in 50% aqueous methanol yield a biphasic Frying plot. The low-temperature process, with a large enthalpy barrier, is postulated to involve a reorganization of the encounter complex through desolvation. ... [Pg.49]
