Question

4. The professor drinks 3 shots (20 ml/shot) of tequila in 3 minutes, and each shot contains 40% ethanol by volume. Metabolism of ethanol follows zero-order kinetics with the rate constant k = 10 mL/h. How long will it take to metabolize 2/3 of the ethanol, leaving the equivalent of one shot in the blood, which should be slightly below the legal limit to drive a car or ride a bike?

Answer 1

4 Volume of Volume of one shot - 20 mL three shots - 20x3 = 60m? 40% of each shot is ethanol, Volume of ethanol = 40% of to mi = 40 x 60 = 24 ml 100 2/3 of ethanol = 2x24 = 16 ml Therefore 16 ml, should be metabolised. For zero, order reaction, K=[A] - [A] [A] = Initial concentration [A] - Remaining concentration to time karate constant E [A]. - [A] - 24 ml-8 ml 10 milh - 16 ml - 1.6 h 10 mith Time taken metabolised for 16 ml of is 1.6h. ethanol (2/3 of ethand) to be
