A student studied the clock reaction described in this experiment. She set up Reaction Mixture 2 by mixing 20 mL of 0.010 M KI, 10 mL 0.001 M Na2S2O3, 10 mL 0.040 M KBrO3, and 10 mL 0.10 M HCl using the procedure given. It took about 45 seconds for the color to turn blue.
b. what was the relative rate of reaction (1000/t)?
