Fill out the data table using this information and results.
Calculate the [I-] and [S2O82-] after mixing using the dilution equation (M1V1 = M2V2). Record the concentrations in your data table. Calculate the reaction rate for each of your measured times in M/s using the relationship: rate = 6.30 x 10−4M/∆t. And Using your calculated concentrations and rates, determine the order of reaction with respect to I-
