Kinetics and equilibria for complex formation between palladium(II) and chloroacetate

Original language description

Kinetics and equilibria for the formation of a 1:1 complex between palladium(II) and chloroacetate were studied by spectrophotometric measurements in 1.00 mol.dm-3 HClO4 at 298.2 K. The equilibrium constant, K, of the reaction Pd2+ + HL &lt;=&gt; PdL+ +H+ was determined from multi-wavelength absorbance measurements of equilibrated solutions at variable temperatures and spectra of individual species were calculated. Variable-temperature kinetic measurements gave rate constants for the forward and backward reactions at 298.2 K and ionic strength 1.00 mol. dm-3. From the kinetics of the forward and reverse processes, log(10) K = 0.346 +/- 0.007, Delta H_0 = -7.9 +/- 0.9 kJ.mol-1 and Delta S_0 = - 19.8 +/- 3.0 J.K-1.mol-1 were derived, and these values are in good agreement with the results of the equilibrium measurements. The Specific Ion Interaction Theory was employed for determination of thermodynamic equilibrium constants for the protonation of chloroacetate.
