Alcohol is removed from the bloodstream by a series of metabolic reactions. The first reaction produces acetaldehyde; then other products are formed. The following data have been determined for the rate at which alcohol is removed from the blood of an average male, although individual rates can vary by 25-30%. Women metabolize alcohol a little more slowly than men: [CH,OH] (M) 4.4 x 10-2 3.3 x 10-2 2.2 x 10-2 Rate (mol/L/h) 2.0 x 10-2 2.0 × 10-2 2.0 x 10-2 Determine the rate equation, the rate constant, and the overall order for this reaction.

3. A midnight dumper discharged a tank truck full of industrial waste in a gravel pit. The truck was spotted there 3 days ago, and a pool of pure waste remains. A laboratory technician determined that the waste has a 5-day BOD of 80 mg/L with a rate constant of 0.1/day. Three factories in the vicinity generate organic wastes: a winery (ultimate BOD = 275 mg/L) a vinegar manufacturer (ultimate BOD = 80 mg/L) and a pharmaceutical company (ultimate BOD = 200 mg/L). Using the information, determine the source of the waste.
