Question

Calculate the reaction rate [I₂] M/s for run 1 (addition of beaker 1 to flask 1) if it takes 65 seconds given the following data:

Solutions	Flask 1	Flask 2	Flask 3
0.055 M KI	25.0 mL	25.0 mL	12.5 mL
1% starch	5.00mL	5.00mL	5.00mL
0.449 M Na₂S₂O₃	5.50 mL	5.50 mL	5.50 mL
1.04 M H₂SO₄	5.00 mL	5.00mL	5.00mL
0.065 M NaCl	0	0	10.0 mL

and

Solutions	Beaker 1	Beaker 2	Beaker 3
0.049 M H₂O₂	25.0 mL	12.5 mL	25.0 mL
deioinized water	0	12.5 mL	0

You will need to calculate the [I₂] from [S₂O₃^2-] using I₂(aq) + 2 S₂O₃^2-(aq) → 2I^-(aq) + S₄O₆^2-(aq)

Then calculate the rate of the reaction [I₂]M/ time(s)

Give your answer as the coefficient (to 2 decimal places) only for your answer written in scientific notation. For example if your answer is 0.000294 = 2.94 x 10^-4 you would input your answer as 2.94.
