Kinetic Parameters of Ternary Complex of Copper(II) with Amino Acids using Thermogravimetric Analysis

Abstract

1 : 1 : 1 Ternary complex of copper(II) using proline and leucine has been synthesized. Kinetic parameters such as apparent activation energy, frequency factor and entropy of decomposition of complex have been determined employing the methods of Sharp- Wentworth and Coats-Redfern using non-isothermal thermogravimetric curves. The values obtained for activation energy, entropy of activation and frequency factor as calculated from Sharp-Wentworth and Coats-Redfern method are in good agreement with each other. The apparent energy of activation, frequency factor and entropy are 9.338 kJ mol^-1, 0.2630 s^-1, and -31.24 J mol^-1 K^-1 respectively.
