Question

The reaction S₂O₈^2-(aq) + 3 I^-(aq) 2 SO₄^2-(aq) + I₃^-(aq) was studied at a certain temperature with the following results:

Experiment	[S₂O₈^2-(aq)] (M)	[I^-(aq)] (M)	Rate (M/s)


1	0.0406	0.0406	7.60e-06
2	0.0406	0.0812	1.52e-05
3	0.0812	0.0406	1.52e-05
4	0.0812	0.0812	3.04e-05

(a) What is the rate law for this reaction?

Rate = k [S₂O₈^2-(aq)] [I^-(aq)]Rate = k [S₂O₈^2-(aq)]² [I^-(aq)] Rate = k [S₂O₈^2-(aq)] [I^-(aq)]²Rate = k [S₂O₈^2-(aq)]² [I^-(aq)]²Rate = k [S₂O₈^2-(aq)] [I^-(aq)]³Rate = k [S₂O₈^2-(aq)]⁴ [I^-(aq)]

(b) What is the value of the rate constant?

(c) What is the reaction rate when the concentration of S₂O₈^2-(aq) is 0.0715 M and that of I^-(aq) is 0.0834 M if the temperature is the same as that used to obtain the data shown above?
