چکیده
where k, is the rate constant for the electron transfer process, K1 the equiiibrium constant for dissociation of [Cr(Lh(H20h+l to [Cr(Lh(H20)(0H)] + W, and K5 the pre-equilibrium format ion constant. Values of k2 = 2.93xl0s• K1 = 6.26 x 10--4 mol dmand K5 = 88.4 1 dm mor 1 have been obtained at 30°C and I= 0.2 mol dmThermodynamic activation parameters have been calculated. It is proposed that electron transfer proceeds through an inner-sphere mechanism via coordination of 104to chromium(III).

Inner-sphere oxidation of ternary iminodiacetatochromium(III) complexes involving DL-valine and L-arginine as secondary ligands. Isokinetic relationship for the oxidation of ternary iminodiacetato-chromium(III) complexes by periodate
BACKGROUND In this paper, the kinetics of oxidation of [CrIII(HIDA)(Val)(H2O)2]+ and [CrIII(HIDA)(Arg)(H2O)2]+ (HIDA = iminodiacetic acid, Val = DL-valine and Arg = L-arginine) were studied. The choice of ternary complexes was attributed to two considerations. Firstly, in order to study the effect of the secondary ligands DL-valine and L-arginine on the stability of binary complex [CrIII(HIDA)(...
متن کاملKinetic, mechanistic and thermodynamic investigations on Iridium (III) catalyzed oxidation of D-Mannitol by N-chloro-p-toluenesulfonamide in perchloric acid medium
The present paper deals with the kinetics and mechanism of homogeneously Ir(III) chloride catalyzed oxidation of D-mannitol by chloramine-T [CAT] in perchloric acid medium in the temperature range of 30 to 45 0C. The reaction is carried out in the presence of mercuric acetate as a scavenger for chloride ion. The experimental results show first order kinetics with respect to the oxidant [CAT] an...
متن کاملThe Kinetics and Mechanism of Oxidation of the N-Substituted Urea-Titanium (III) Complexes by Iodine (AS I-3) in Ethanol and Acetonitrile
The oxidation of complexes of Ti(III), (TiL6)3+ (L=ur, Meur, DMeur, DEture, N-Bu-ur, and Phur), by iodine as I3- in ethanol and acetonitrile solutions, appears to proceed as a second order reaction and is much faster in ethanol solution (where solvolysis occurs) than in acetonitrile. The enthalpy of activation appears to decrease as ligand's size ...
متن کاملThe Gas Phase Oxidation of Acetaldehyde Reaction Mechanism and Kinetics
The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...
متن کاملRapid Determination of Chromium (M)lli Natural Water and Industrial Effluents Using Kinetic Speetrophotometric Method
A new simple arid rapid catalytic kinetic method for determination of trace amounts of chromium (110 isdescribed. The method is based on the catalytic effect of chromium (III) on the reduction of Methylene blue byascorbic acid in acidic media. The reaction monitored smectrophotomenically by measuring the decrease ofabsorbance at 664 nm at 25 C. The fixed-time method was used for the first 300 s...
