Rearranging and taking the logarithm of both sides yields

$ln(\frac{C_{AD}-C_C}{C_{A0}})=-kt$

We see that a plot of $ln[\frac{C_{A0}-C_C}{C_{A0}}]$ as a function of $t$ will be a straight line with a slope $-$k$.$ Using Table E$4-1\mathrm{.}1,$ we can construct Table E$4-1\mathrm{.}3$ and use Excel to piot $\frac{\text{:}lni{C}_{A0}-C_C}{C_{A0}}$ as a function of $t.$
