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?

Identifying Reaction Order

Q. Fluorine-18 undergoes positron emission with a half-life of 1.10 × 10 2 minutes. If a patient is given a 248 mg dose for a PET scan, how long will it take for the amount of fluorine-18 to drop to 83 mg? (Assume that none of the fluorine is excreted from the body.)
