1. You are measuring the five-day BOO in a seeded test. You add 10 mL of sample and 5 mL of seed to bottle #1 (the sample bottle) and 20 ml of seed to bottle #2 (the seed bottle). The initial and 5-day DO in bottle #1 is 8.2 mg/I and 2.5 mg/l, respectively. The initial and 5-day DO in bottle #2 is 8.2 mg/I and 4 mg/I, respectively.

a. What is the 5-day BOO? (140 ppm)

b. What is the ultimate BOO of the sample with a rate constant of 0.15 day1? (264 ppm)

c. Plot the DO vs. time in the seed bottle. Label each axis appropriately. The time should be from 0 to 40 days. Assume the rate constant is still 0.15 day^-1. What is the DO at t =infinity?
