- 中文摘要: The kinetics of oxidation of the chromium(III)-guanosine 5-monophosphate complex, [CrIII(L)(H2O)4]3+ (L = guanosine 5-monophosphate) by periodate in aqueous solution to CrVI have been studied spectrophotometrically over the 25-45 °C range. The reaction is first order with respect to both [IO4-] and [CrIII], and increases with pH over the 2.38-3.68 range. Thermodynamic activation parameters have been calculated. It is proposed that electron transfer proceeds through an inner-sphere mechanism via coordination of IO4- to chromium(III).
