Question

The initial concentration of a drug decomposing according to first order kinetics is28 units/mL. The specific decomposition rate, k, obtained from an Arrhenius plot is 2.09 × 10^-5 hr^-1 at room temperature, 25°C. Previous experimentation has shown that when the concentration of the drug falls below 15 units/mL it is not sufficiently potent for use and should be removed from the market. What expiration date should be assigned to this product?

• A. Approximately 31,012.15 hours
• B. Approximately 32,225.56 hours
• C. Approximately 27.216.12 hours
• D. Approximately 29,869.23 hours

Answer 1

The Correct Option is D

The correct option is (D):Approximately 29,869.23 hours
