If \(\mathrm{E}^{\circ}\left(\mathrm{Ag}^{+}{ }_{(\mathrm{aq})} \mid \mathrm{Ag}_{(\mathrm{s})}\right)=+0.80 \mathrm{~V}\)
What is potential developed for \(\mathrm{Ag}_{(\mathrm{s})} \rightarrow \mathrm{Ag}^{+1}(0 \cdot 01 \mathrm{M})+\overline{\mathrm{e}}\) at 298 K ?

  1. A \(+0.9184 \mathrm{~V}\)
  2. B \(-0.9184 \mathrm{~V}\)
  3. C \(+0.6816 \mathrm{~V}\)
  4. D \(-0.6816 \mathrm{~V}\)
Verified Solution

Answer & Solution

Correct Answer

(D) \(-0.6816 \mathrm{~V}\)

Step-by-step Solution

Detailed explanation

\( \mathrm{E}_{\text{ox}}^{\circ} = - \mathrm{E}^{\circ}\left(\mathrm{Ag}^{+}{ }_{(\mathrm{aq})} \mid \mathrm{Ag}_{(\mathrm{s})}\right) = -0.80 \mathrm{~V} \) \( \mathrm{E} = \mathrm{E}_{\text{ox}}^{\circ} - \frac{0.0592}{n} \log [\mathrm{Ag}^{+}] \)
