What's the question?


1) what evidence is there that the reaction (iodine clock) takes place in more than one step?
2) propose a possible two- or three-step mechanism for this reaction assuming that the first step is the rate-determining step.

1) You've got 3 reactants and it's unlikely they'll all react at the same time
2) can be anything so long it fits the equation. Do you have the rate equation
