1. Bromobutane reacts with water to form 1-butanol according to the following equation. ${\mathrm{C}}_4{\mathrm{H}}_9\mathrm{Br}(\mathrm{aq})+2{\mathrm{H}}_2\mathrm{O}(\mathrm{l})?{\mathrm{C}}_4{\mathrm{H}}_9\mathrm{OH}(aq)+{\mathrm{H}}_3{\mathrm{O}}^{+}(aq)+{\mathrm{Br}}^{?}(aq)$ The following is a proposed mechanism for the reaction. $\begin{array}{ll}{\mathrm{C}}_4{\mathrm{H}}_9\mathrm{Br}(aq)?{\mathrm{C}}_4{\mathrm{H}}_9^{+}(aq)+{\mathrm{Br}}^{?}(aq)& \text{ slow }\\ {\mathrm{C}}_4{\mathrm{H}}_9{}^{+}(aq)+{\mathrm{H}}_2\mathrm{O}(l)?{\mathrm{C}}_4{\mathrm{H}}_9{\mathrm{OH}}_2{}^{+}(aq)& \text{ fast }\\ {\mathrm{C}}_4{\mathrm{H}}_9{\mathrm{OH}}_2{}^{+}(aq)+{\mathrm{H}}_2\mathrm{O}(h)?{\mathrm{C}}_4{\mathrm{H}}_9\mathrm{OH}(aq)+{\mathrm{H}}_3{\mathrm{O}}^{+}(aq)& \text{ fast }\end{array}$ Determine the overall rate law for this proposed mechanism. (Rate expressions take the general form: rate $=k?[\mathrm{A}{]}^{\mathrm{a}},[\mathrm{B}{]}^{\mathrm{b}}$.)
