2. The reaction between ethyl iodide and hydroxide ion in ethanol solution, ${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{I}(\text{ afc })+{\mathrm{OH}}^{+}?{\mathrm{C}}_2{\mathrm{H}}_6\mathrm{OH}(\mathrm{I})+{\mathrm{I}}^{(\text{alc })}$ has an activation energy of $86.8\mathrm{kJ}/\mathrm{mol}$ and a frequency factor of $2.10\times 10^{11}{\mathrm{M}}^{?1}{\mathrm{s}}^{?1}$. a. Predict the rate constant for the reaction of $35^{?}\mathrm{C}$. b. A solution of $\mathrm{KOH}$ in ethanol is made by dissolving $0.335\mathrm{g}\mathrm{KOH}$ in ethanol to form $250.0\mathrm{mL}$ of solution. Equal volumes of the two solutions are mixed. Assuming the feaction is first order in each reactant, what is the initial rate at 35 ${}^{?}\mathrm{C}$ ? c. Which reagent in the reaction is limiting, assuming the reaction proceeds to completion? d. Assuming the frequency factor and activation energy do not change as a function of temperature, calculate the rate constant for the reaction at $50^{?}\mathrm{C}$.
