Question

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^-1s^-1. If the initial concentration of BrO^- is 0.60 M, how long will it take one-half of the BrO^- ion to react?

a. 5.3 s

b. 30. s

c. 3.4 × 10^-2 s

d. 12 s
