To determine the rate constants and kinetic parameters on the reaction between 1 10-Phenantroline, as a bidentate ligand and cis-[Pt(p-FC6H4)2(SMe2)2] complex in acetone and benzene solvents, the reactions were monitored by UV-Vis spectrophotometer. The pseudo-first-order rate constants (kobs=k1+k2[phen]) of the reaction were derived, and the values of the first and second order rate constants (k1 and k2) calculated using standard equations. The reactions were carried out in the range of 20 to 50℃ The second-order rate constant dependency on the temperature was in agreement with the Arrhenius equation, providing the relevant plots to calculate the activation energy of all the reactions. The ΔH#(KJ.mol-1) and ΔS#(J.mol-1.K-1) were obtained 28.677 and –165.9 respectively in benzene. These values were 56.723 and -72.2 respectively, in acetone. The product synthesizing was confirmed using elemental (CHN) and spectral (IR) analysis.
