Answer to Question #87922 in Chemistry for sirina

Question

A new drug is being developed by an important pharmaceutical company. It has been noted that the interaction in solution between the newly developed drug and a common excipient leads to formation of potentially toxic degradants of the drug. It was determined that the degradation of the newly developed drug follows first order kinetics with the time taken to decrease the concentration to 45% of the initial (4.5 mM) being 2 days.

a) Calculate the rate constant for the first order degradation reaction. Use appropriate units. (30%)

b) Determine the half-life for this degradation reaction. (20%)

c) Calculate the rate constant if the reaction had followed zero order kinetics. Use appropriate units. (25%)

d) Calculate the rate constant if the reaction had followed second order kinetics. Use appropriate units. (25%)
