چکیده
|
Kinetics of reduction of iron (iii) kojic acid complex by ascorbic acid has been carried out using photodiode array spectrophotometer over the ranges: 4.0 ≤ ph ≤ 5.5 and 5.0 ≤ t ≤ 25.0 °c at ionic strength 0.2 m under pseudo-first order conditions by stopped-flow technique. rate of the reaction was found to be ph dependent. the redox reaction followed the saturation kinetics. the rate law is deduced as follows: {equation presented} the activation parameters of this reaction were determined. a mechanism consistent with this rate law has been proposed.
