You mix together in the proper manner the following VOLUMES:

0.0100 M Potassium iodide...9.2 mL
0.0010 M Sodium thiosulfate...6.5 mL
Distilled water...16.8 mL
0.0400 M Potassium Bromate...13.9 mL
0.100 M Hydrochloric acid...6.1 mL
Using the rate constant and rate equation
constant is 14,000
and the rate equation is RATE = ([ Na2S2O3]/time) = k [I-]a [BrO3-]b [HCl]c
