9.10 Cell Potential Under Nonstandard Conditions
A galvanic cell is constructed under standard conditions at \(298\text{ K}\) based on the following balanced equation:
\[ \text{Cu(s)} + 2\,\text{Ag}^+\text{(aq)} \rightarrow \text{Cu}^{2+}\text{(aq)} + 2\,\text{Ag(s)} \quad E^\circ_{\text{cell}} = +0.46\text{ V} \]
A student modifies the cell by adding an equal volume of distilled water to both half-cell compartments and stirring thoroughly. Which of the following statements best predicts and justifies the effect of this modification on the cell potential, \(E_{\text{cell}}\)?
\[ \text{Cu(s)} + 2\,\text{Ag}^+\text{(aq)} \rightarrow \text{Cu}^{2+}\text{(aq)} + 2\,\text{Ag(s)} \quad E^\circ_{\text{cell}} = +0.46\text{ V} \]
