Consider the reaction of the peroxydisulfate ion (S₂O²-) with
the iodide ion (I) in an aqueous solution:
S₂O² (aq) +31-(aq)→2SO4²¯ (aq) + I₂¯(aq)
2-
At a particular temperature, the rate of disappearance of S₂O²-
varies with reactant concentrations in the following manner:

?
O I is one-third the rate of disappearance of S₂ Og²-.
The rate of disappearance of $₂0,² is one-third the rate of disappearance of I.
O S₂O² is equal to the rate of disappearance of I
