A student studied the clock reaction described in this experiment. She set up a reaction mixture by mixing 10mL of 0.010 M KI, 10mL of 0.0010 M Na2S2O3, 20mL of 0.040 M KBrO3 and 10 mL of 0.10 M HCL using the procedure given in this experiment. It took 40 seconds for the color to turn blue.
a. Find the concentration of each reactant in the mixture
[I-]= M
[BrO3]= M
[H+]= M
b. Find the relative rate of the reaction
Relative rate= 1000/t.
