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?

Zero$-$order; because of a straight line on a semilog graph.

First Order; because of a straight line on a linear graph.

Zero$-$order; 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 FIRST$-$ORDER process?

The rate is independent of the amount or concentration of the drug.

$2$: The half$-$life is dependent on the amount or concentration of the drug.

$3$: The rate constant is dependent on the amount or concentration of the drug.

$4$: The unit of rate constant is amount $($or concentration$)/$time$.$

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 dissolving$)(A_o$inmg$)$

The rate constant of degradation process in $\{$:$h{r}^{-1})$

The half life of degradation process in $\{$:$hr)$

The concentration of kinetomycin at time zero in $\{$:$m\frac{g}{L})$

III. From the data obtained above or using the graph, please estimate the following:

The amount at a time of in $\{$:$mg)$

The time to reach an amount of in $\{$:$hr)$

The rate constant of degradation process $(Kinh{r}^{-1})$

The initial amount of kinetomycin added to the solution $($at time zero immediately after dissolving$)$ in $mg)$
