ABSTRACT:
The electrochemical Kinetic study of 1, 1′- Dibenzoylferrocene (DBF) at a platinum working electrode in 0.1 mol dm-3 NaClO4 non aqueous medium has been studied by Cyclicvoltammetry. The heterogeneous electron transfer rate constants (ks) and the diffusion coefficients (Do) of DBF were estimated at various temperatures (283 – 323 K) and at different scan rates (0.05 – 0.5 V s-1 ). A calibration curve, linear over the range of 1×10-3 – 9×10-3 mol dm-3 , was plotted at the scan rate of 0.25 Vs-1 . This plot can be used to analyze an unknown sample of the compound. The kinetic data was also used to evaluate the Activation energy (Ea). The thermodynamic parameters such as enthalpy change of activation (ΔH*), Entropy change (ΔS*) and Gibbs free energy change (ΔG*) were also investigated during the study.
