%X The electrochemical Kinetic study of 1, 1¡ä- Dibenzoylferrocene (DBF) at a platinum working electrode in 0.1 mol dm-3 NaClO4non aqueous medium has been studied by Cyclicvoltammetry. The heterogeneous electron transfer rate constants (ks) and thediffusion coefficients (Do) of DBF were estimated at various temperatures (283 ¨C 323 K) and at different scan rates (0.05 ¨C 0.5 Vs-1). A calibration curve, linear over the range of 1x10-3 ¨C 9x10-3 mol dm-3, was plotted at the scan rate of 0.25 Vs-1. This plot canbe 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 (¦¤H*), Entropy change (¦¤S*) and Gibbs free energy change(¦¤G*) were also investigated during the study.
