AP Chemistry
9.9 Cell Potential and Free Energy
9.8 Galvanic (Voltaic) and Electrolytic Cells
A student constructs a galvanic cell operating under standard conditions using silver and lead electrodes submerged in standard \(1.0 \, \text{M}\) nitrate solutions. The relevant standard reduction potentials are given in the table below.
What is the standard cell potential, \(E^\circ_{\text{cell}}\), for the galvanic cell?
| Half-Reaction | \(E^\circ \, \text{(V)}\) |
|---|---|
| \(\text{Ag}^+(\text{aq}) + e^- \rightarrow \text{Ag}(\text{s})\) | \(+0.80\) |
| \(\text{Pb}^{2+}(\text{aq}) + 2e^- \rightarrow \text{Pb}(\text{s})\) | \(-0.13\) |
