    Rate of an Iodine clock reaction.
    I'm doing my pre lab question and one of them states " When the dark color appears, ��[S2O8 2-] = (1/2) ��[S2O3 2-], where ��[S2O3] equals the initial concentration of Na2S2O3". And it asks, why is that statement true?

    The concentration of either of the reactants are not given, so I'm not sure how I will know that it is true.

    Reaction with the most iodine will end faster than the reaction with the least of iodine... starch is constant at 1? Is that correct or it's the other way around?

Iodine clock reaction with S2O3 ion [ 3 Answers ]

In the iodine clock reaction with S2O3 ion I have found that one of the exponents in the reaction rate is 1.55. Can I round it to 2? Or shoud I write it as a fruction 3/2? I know that reaction rate can be a fraction. But it is a fraction in this case? Thank you! :)
