This Data Applies to the Next Three Problems

This data applies to the next three problems.
The initial rate of disappearance of bromine (Br₂) for the reaction shown below was measured for several different concentrations of bromine, CH₃COCH₃, and H⁺ ions. (Note that H⁺ is a catalyst in this reaction - it participates in the reaction but is not itself consumed)

-The rate law for this reaction would be:

A) zero-order in CH₃COCH₃
B) half-order in CH₃COCH₃
C) first-order in CH₃COCH₃
D) second-order in CH₃COCH₃
E) none of the above.
