Kinetic study of electron transfer reaction between bis-acetylacetonatodiaquomanganese (III) perchlorate and thiosulfate,and investigation of factors influencing the electron transfer process

摘要

Bisacetylacetonatodiaquomanganese (III) complex has been prepared in perchloric acid medium.Kinetic order of the reduction of this complex with thiosulfate is established.The reaction follows first order kinetics in complex,fractional order in both thiosulfate and [H~+].The redox mechanism has been explained and the rate law derived.Activation parameters are computed and an outer-sphere mechanism is suggested for the reaction.
