A student assembles the following concentration cell at \(25^\circ\text{C}\), using a \(\text{KNO}_3\text{(aq)}\) salt bridge.

\(\text{Ag(s)}\mid\text{Ag}^+\text{(aq)},\ 0.010\text{ M}\parallel\text{Ag}^+\text{(aq)},\ \text{variable concentration}\mid\text{Ag(s)}\)

The positive terminal of a voltmeter is connected to the right electrode. The student varies the right-half-cell concentration and graphs the measured potential difference, \(E_{\text{right}}-E_{\text{left}}\), as a function of \(\log\!\left(\dfrac{[\text{Ag}^+]_{\text{right}}}{[\text{Ag}^+]_{\text{left}}}\right)\).

Which statement correctly interprets point P and predicts the spontaneous direction of electron flow through an external wire?
