| Abstract: | Kinetics of silver(I) catalyzed oxidation of valine
with
cerium(IV) has been studied in perchloric acid medium. A
decrease in rate with increase in [Ce(IV)] is observed. The
detailed quantitative analysis of this behavior is presented on the basis of
dimerization of cerium(IV). The reaction exhibits
fractional dependence on valine which is explained on the basis of formation of
an adduct with silver(I). A plausible reaction
mechanism is given and the rate law is derived as follows: , where k is
the observed second order rate constant. |
