Chapter 14, Problem 14.32(choose chapter or problem)
The reaction between ethyl bromide \(\left(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{Br}\right)\) and hydroxide ion in ethyl alcohol at 330 K, \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{Br}(\text { alc })+\mathrm{OH}^{-}(\text {alc }) \longrightarrow \mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}(l)+\mathrm{Br}^{-}(\text {alc })\), is first order each in ethyl bromide and hydroxide ion. When \(\left[\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{Br}\right]\) is 0.0477 M and \(\left[\mathrm{OH}^{-}\right]\) is 0.100 M, the rate of disappearance of ethyl bromide is \(1.7 \times 10^{-7} \mathrm{M} / \mathrm{s}\).
(a) What is the value of the rate constant?
(b) What are the units of the rate constant?
(c) How would the rate of disappearance of ethyl bromide change if the solution were diluted by adding an equal volume of pure ethyl alcohol to the solution?
