- 11. Blood Alcohol Content This question is about elimination of al- cohol from the blood. The elimination of ethanol from the blood is generally believed to have zeroth order kinetics, meaning that the rate of elimination is a constant, independent of the concen- tration. (a) Explain why it follows if no alcohol is being drunk, the blood alcohol concentration is described by the differential equation: dc -ko , c(0) = co dt where ko and co are both constants, which vary from person to person and depend on how much alcohol the patient has consumed.
