Identifying Reaction Order

Q. In aqueous solution, hypobromite ion, BrO–, reacts to produce bromate ion, BrO3–, and bromide ion, Br–, according to the following chemical equation: 3 BrO–(aq) → BrO3–(aq) + 2 Br–(aq) A plot of 1/[BrO–] vs. time is linear and the slope is equal to 0.056 M–1 s–1. If the initial concentration of BrO– is 0.80 M, how long will it take one-half of the BrO– ion to react?
