Question 1

The oxidation of Cr³⁺ to CrO₄^2– can be accomplished using Ce⁴⁺ in a buffered solution. The following data were obtained:

Relative Initial Rate	[Ce⁴⁺]₀	[Ce³⁺]₀	[Cr³⁺]₀
1	2.0 × 10^–3	1.0 × 10^–2	3.0 × 10^–2
2	4.0 × 10^–3	2.0 × 10^–2	3.0 × 10^–2
4	4.0 × 10^–3	1.0 × 10^–2	3.0 × 10^–2
16	8.0 × 10^–3	2.0 × 10^–2	6.0 × 10^–2

Determine the order in the rate law of the species Cr³⁺.
