Finding the order for each reactant 4. Finding the rate-determining step. 5. Proposing a mechanism for the reaction. 6. Using Arrhenius' equation to find the activation enthalpy. Background The basic reaction for this can be illustrated with the following equation: 3I-(aq) + H2O2(aq) + 2H+(aq) > I3-(aq) + 2H2O(aq) (1) The half equations for this reaction can be written as follows: 3I- ? I3- + 2e- H2O2 + 2H+ + 2e- ? 2H2O This reaction demonstrates that iodide ions are oxidised by hydrogen peroxide to tri-iodide ions...

Thus, the iodine that is formed in reaction (1) is immediately transformed into iodide ion and we do not see the blue-black colour of the starch-iodide complex until all of the thiosulphate ion has reacted with I 2(aq) and is exhausted. I3- (aq) + starch ? Starch-I5- complex + I-(aq) Once the thiosulphate ion has been exhausted, the tri-iodide ion can react with the starch, forming the Starch-I5- complex, giving the blue-black colour...
