Question

What is the standard electrode potential at 298 K for the reaction:
\[ \text{Cu}^{2+} + \text{e}^- \rightarrow \text{Cu}^+ \] Given: \( E^0_{\text{Cu}^{+}/\text{Cu}} = 0.5 \, \text{V} \) and \( E^0_{\text{Cu}^{2+}/\text{Cu}} = 0.335 \, \text{V} \)

• A. 0.34 V
• B. 0.17 V
• C. 0.492 V
• D. 0.410 V

Hint:

When calculating electrode potentials, remember that the Nernst equation takes into account both the concentration of the ions involved and the temperature, which may affect the cell potential.
