1 The Iodine Clock Reaction Chemistry LibreTexts . This reaction rate is a measure of how much iodine was produced in the time it took for the reaction to turn blue (i.e., time taken to react with all of the thiosulfate present). Reaction Orders In this experiment we use the initial rate method to find the order of the reaction with respect to persulfate ( m ) and the order of the reaction with respect to iodide ( n ).
