The following initial rate data are for the oxidation of arsenate ion by cerium(IV) ion in aqueous solution:

AsO₃^3- + 2 Ce⁴⁺ + H₂O -------> AsO₄^3- + 2 Ce³⁺ + 2 H⁺

Experiment	[AsO₃^3-]_o, M	[Ce⁴⁺]_o, M	^{Initial Rate, M s-1}
1	4.13×10^-2	0.463	4.79×10^-3
2	8.26×10^-2	0.463	9.58×10^-3
3	4.13×10^-2	0.926	1.92×10^-2
4	8.26×10^-2	0.926	3.83×10^-2
