Expert Solution
Step 1

To determine the order of the reaction for KIO3 using the initial rates method. 

The initial rate for the reaction of KIO3 at different concentration is given as follows:

Trial [KIO3] [HSO3-] Rate (M/s)
1 0.02 M 0.01 M 2.04 ×10-5 M/s
2 0.04 M 0.01 M 4.0 ×10-5 M/s
3 0.06 M 0.01 M 5.92 × 10-5 M/s
