Blood alcohol content (BAC) is a measure of the amount of alcohol in the blood stream of a person. In Pennsylvania, drivers of cars are required to have a BAC lower than 0.08 %. This corresponds to 80 mg of alcohol for every 100 mL of blood. The following data shows the BAC as a function of time for an individual. A typical adult would have this starting concentration of alcohol if about three drinks are consumed in an hour. No additional drinks are consumed after testing began. Time (hours ) BAC % 0 0.12 1.5 0.097 2.5 0.083 3.5 0.067 5.0 0.045 6.0 0.030 The values presented in this table are representative values, actual rates of alcohol metabolism depend on a variety of factors. (a) What is the reaction order for metabolism of alcohol in the human body? Prepare three graphs (0th, 1st, and 2nd order) using the above data to support your answer. (b) What is the rate constant for metabolism of alcohol using the above data? (c) Impaired functioning has been shown for BAC of 0.02 %. How much time will it take for the BAC level in the person above to be less than 0.02%? 3
