Does any1 happen to know the order of reaction for potassium iodide and potassium peroxodisulphate?! I've carried out an experiment but it gives mixed results as half show 1st order and half show 2nd order. Never have been good at practicals!

I know what the rate equation is supposed to be, but rather than tell you what it is, I'm gong to ask you to show your experimental results, to make sure that you did not in fact, just make some calculation error.
