I. Please answer the following two multiple choice questions:
Please plot the above data on both linear and semilog graphs. What is the order of degradation process of kinetomycin? Why?
Zeroorder; because of a straight line on a semilog graph.
First Order; because of a straight line on a linear graph.
Zeroorder; because of a straight line on a linear graph.
First Order; because of a straight line on a semilog graph.
Which of the following statements is CORRECT for a FIRSTORDER process?
The rate is independent of the amount or concentration of the drug.
: The halflife is dependent on the amount or concentration of the drug.
: The rate constant is dependent on the amount or concentration of the drug.
: The unit of rate constant is amount or concentrationtime
II From the appropriate graph or using linear regression analysis, please estimate the following parameters:
The initial amount of kinetomycin added to the solution at time zero immediately after dissolvinginmg
The rate constant of degradation process in :
The half life of degradation process in :
The concentration of kinetomycin at time zero in :
III. From the data obtained above or using the graph, please estimate the following:
The amount at a time of in :
The time to reach an amount of in :
The rate constant of degradation process
The initial amount of kinetomycin added to the solution at time zero immediately after dissolving in
