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 constant for this reaction is:

A) smaller than 1 x 10^-5
B) between 1 x 10^-5 and 1x 10^-4
C) between 1 x 10^-4 and 1 x 10^-3
D) between 1 x 10^-3 and 1
E) greater than 1
