A pharmacist must calculate the shelf life for an antibiotic. The antibiotic is stored as a solid and a fresh solution must be prepared for the patient. The antibiotic is unstable in solution and decomposes according to the following data: Time (days) [Antibiotic] (mol/L) 1.24 x 10-2 10. 0.92 x 10-2 0.68 x 10-2 30. 0.50 x 102 40. 0.37 x 10-2 This is a first order process. Question 1 Calculate the half-life for the antibiotic. The units should be in days and should be calculated to three significant figures. Submit Answer Tries 0/45 Question 2 If you start with a 1.0 M solution, how long would it take for 55% of the antibiotic to decompose? The answer should be in days and should be calculated to three significant figures.
The breakdown of drugs in the body follow first order kinetics. . The time taken for half of the original concentration of the drug to remain in our system is called the half life of the drug.
What is half life?
When we take drugs, our system begins a whole long process of detoxification and breakdown of the drugs. The time taken for half of the original concentration of the drug to remain in our system is called the half life of the drug.
The specific figures are not shown here hence the question is incomplete. However, the breakdown of drugs in the body follow first order kinetics.
