2. To complete the following table:
a. Determine the initial concentration (molarity) of each reagent using the equation (note:
these values will be exactly the same for your experimental data):
Mstock Vstock -Minital total
The Mstock and Vstock for each reagent are given in problem 1 (for example, for KI, the Mack
is 0.010 M and Vstock is 1 ml for mixture 1). The total volume is 5 mL for each mixture.
b. Calculate the rate of the reaction using the equation (note: these rates may differ slightly
from the data collected during your experiment)
