The kinetics of electron transfer from L-ascorbic acid to (EDTA)RuV= O-1 (EDTA= ethylenediaminetetraacetate anion) was studied spectrophotometrically by monitoring the disappearance of the characteristic oxo peak (λmax=393 nm) of the oxo complex 1 as a function of total concentration of ascorbic acid, pH (1.0-6.0), ionic strength (0.1-0.3 M) and temperature (25 - 45 °C). Activation parameters (ΔH≠ and ΔS≠) were determined and the experimental results are discussed in terms of probable mechanism involving a rate-deterimining outer sphere electron transfer from L-ascorbic acid to the RuV-oxo complex. © 1991.
