Question
Theophylline is a pharmaceutical drug that is sometimes used to help with lung function. You observe a case where the initial lab results indicate that the concentration of theophylline in a patient's body decreased from 8.0 × 10¬ª M to 4.0 × 10¬ª M in 24 hours. In another 12 hours the drug concentration was found to be 2.0 x 10* M. What is the value of the rate constant for the metabolism of this drug in the body? Rate constant = mol/L · h
