Consider the electrochemical cell: \(\text{Zn(s)}\,|\,\text{Zn}^{2+}(0.010\,\text{M})\,||\,\text{Cu}^{2+}(0.50\,\text{M})\,|\,\text{Cu(s)}\). Standard reduction potentials are \(E^{\circ}(\text{Zn}^{2+}/\text{Zn}) = -0.76\) V and \(E^{\circ}(\text{Cu}^{2+}/\text{Cu}) = +0.34\) V. At 298 K, calculate the cell potential using the Nernst equation and state whether the overall reaction is spontaneous.

Answer Options

A. 0.95 V, spontaneous
B. 1.15 V, non-spontaneous
C. 0.85 V, spontaneous
Correct Answer D. 1.15 V, spontaneous
Correct Answer
D
Correct Option:
1.15 V, spontaneous
