The iodine liberation process is significantly affected by the amount of acid, that of potassium iodide added, the waiting time for the liberation, and light; therefore, the process plays a key role for the accuracy of the titration results. For a 10\(^0\) rise in temperature, time of reaction is halved i.e as temperature increases from 25 - 35, time of reaction is halved from 72 to 36. However, recall that rate of reaction = \(\frac{1}{time of reaction}\) ⇒ They are inversely proportional. Which means for a 10\(^0\) rise in temperature, if time of reaction is halved, then rate of reaction will be doubled.
