Two kinetics trials are performed at the same temperature with [S2O82-] held constant. The first trial has a reaction time of 84 seconds. For the second trial, the [I ̶ ] is four times that of the first trial (the concentration is quadrupled), and the reaction time is 22 seconds. If the change in concentration of S2O82- is 4.3x10 ̶ 5 M for both trials, what is the reaction order with respect to iodide ion?
