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 rate
constant, k, is equal to 0.056
M-1s-1. If the initial concentration of
BrO- is 0.80 M, how long will it take* the concentration
of the BrO- ion to be 0.40 M?
