17. The reaction \[ \mathrm{CHCl}_{3}(\mathrm{~g})+\mathrm{Cl}_{2}(\mathrm{~g}) \rightarrow \mathrm{CCl}_{4}(\mathrm{~g})+\mathrm{HCl}(\mathrm{~g}) \] has been proposed to occur by the following mechanism. \[ \begin{array}{l} \mathrm{Cl}_{2} \underset{\mathrm{k}_{-1}}{\stackrel{\mathrm{k}_{1}}{\rightleftharpoons}} 2 \mathrm{Cl} \xrightarrow{\text { (fast) }} \\ \mathrm{CHCl}_{3}+\mathrm{Cl} \xrightarrow{k_{2}} \mathrm{HCl}+\mathrm{CCl}_{3} \text { (slow) } \\ \mathrm{CCl}_{3}+\mathrm{Cl}_{2} \xrightarrow{k_{3}} \mathrm{CCl}_{4} \text { (fast) } \end{array} \] What is the rate law predicted by this mechanism? A) Rate $ =\mathrm{k}\left[\mathrm{CHCl}_{3}\right]\left[\mathrm{Cl}_{2}\right] $ B) Rate $ =\mathrm{k}-1[\mathrm{Cl}]^{2} $ C) $ \mathrm{Rate}=\mathrm{k}_{1}\left[\mathrm{Cl}_{2}\right] $ D) Rate $ =\mathrm{k}_{3}\left[\mathrm{CCl}_{3}\right][\mathrm{Cl}] $ E) Rate $ =\mathrm{k}_{2}\left(\mathrm{k}_{1} / \mathrm{k}_{-1}\right)^{1 / 2}\left[\mathrm{CHCl}_{3}\right]\left[\mathrm{Cl}_{2}\right]^{1 / 2} $
