The UV-visible absorption bands of the charge transfer (CT) complex of N, N, N', N'-tetramethyl-4,4'-diamino-benzophenone with iodine in methanol at 30°C have been studied. The value of KAD, εAD and ECT were calculated for this complex. The value of the equilibrium constant, KAD, for the above complex reaction was calculated as 28.85m3·mol-1. The value of the molar extinction coefficient of the CT complex, εAD, was also calculated as 1171m2·mol-1 for λmax = 602 nm and the absorption band energy ECT of the complex was found to be 2.06 e.v. The ionization potential of the electron donor was also obtained spectroscopically and found to be 6.284 e.v. The rate constant obtained for the forward reaction is 3.624 x 10-5M1/2s-1 and for the reverse reaction is 1.256 x 10-6s-1. Finally, the half-life value for the above reaction was graphically calculated and shown to be 1.549 day. The kinetics of the above reaction were studied showing the reaction to be a half-order reaction. The values of rate constants and half-life were calculated. |
