Question:

For the following half-reaction, \(\mathscr{E}^{\circ}=-2.07 \mathrm{~V}\) :

\[\mathrm{AlF}_{6}{ }^{3-}+3 \mathrm{e}^{-} \longrightarrow \mathrm{Al}+6 \mathrm{~F}^{-}\]

Using data from Table 11.1, calculate the equilibrium constant at \(25^{\circ} \mathrm{C}\) for the reaction

\[\mathrm{Al}^{3+}(a q)+6 \mathrm{~F}^{-}(a q) ightleftharpoons \mathrm{AlF}_{6}{ }^{3-}(a q)\]
