The reaction is very fast and of the second order, having half-life 300 seconds and rate constant 6.81 M-1-1 at 30.2C. The reaction is fast and hydrodynamic voltammetry, a special technique to follow the rapid iodination kinetics is employed. he energy of activation, entropy change in the reaction and the frequency factor in the reaction are evaluated. The kinetic and related thermodynamic data obtained are used to comment on the reactivity of the substrate. Copyright@ International Science Community Association
