Exhibit 18-3 the Following Question(s) Pertain to the Reaction of Propene

Exhibit 18-3 The following question(s) pertain to the reaction of propene (C3CHCH2) with hydrochloric acid. $\mathrm{HCl}+\mathrm{C}_{3} \mathrm{CHCH}_{2} \leftrightarrows \mathrm{CH}_{3} \mathrm{CHClCH}_{3}$ A proposed mechanism for this chemical reaction is $\begin{array}{ll}\mathrm{HCl}+\mathrm{HCl} \leftrightarrows \mathrm{H}_{2} \mathrm{Cl}_{2}& \text { (fast, equilibrium) } \\\mathrm{HCl}+\mathrm{C}_{3} \mathrm{CHCH}_{2} \leftrightarrows \mathrm{CH}_{3} \mathrm{CHClCH}_{3}{ }^{*} & \text { (fast, equilibrium) } \\\mathrm{CH}_{3} \mathrm{CHClCH}_{3}{ }^{*}+\mathrm{H}_{2} \mathrm{Cl}_{2} \rightarrow \mathrm{CH}_{3} \mathrm{CHClCH}_{3} \rightarrow 2 \mathrm{HCl} & \text { (slow) }\end{array}$ Refer to Exhibit 18-3. What is the predicted rate law for this mechanism?

A) $\frac{\mathrm{k}_{1}}{\mathrm{k}_{-1}} \frac{\mathrm{k}_{2}}{\mathrm{k}_{-2}} \mathrm{k}_{3}[\mathrm{HCl}]^{3}\left[\mathrm{CH}_{3} \mathrm{CHCH}_{2}\right]$
B) k₃[H₂Cl₂][CH₃CHClCH3^*]
C) k₂[HCl][CH₃CHCH₂]
D) none of the above
