Abstract

|
|
Proton behavior was investgated for the redox reaction of trans-[Co(en)2(NO2)Cl]+ with aqueous Fe(Ⅱ) in acidic solution by UV/vis-spectrophotometric method. The reaction order of proton is first one and the rate constant(kH+) is 6.7 × 10-1 L2/mol2·min. The values of Ea, △H≠, △S≠ are 14.5 Kcal/mol, 13.8 Kcal/mol and -18.3e.u., respectively. As the result of analysis of kinetic data, it has been found that this reaction proceeds through inner-sphere mechanism.
