A galvanic cell is set up as \(\text{Zn}|\text{Zn}^{2+}(0.010\,\text{M})\,||\,\text{Cu}^{2+}(0.10\,\text{M})|\text{Cu}\) at 25 °C. Standard electrode potentials are \(E^{\circ}(\text{Cu}^{2+}/\text{Cu}) = +0.34\,\text{V}\) and \(E^{\circ}(\text{Zn}^{2+}/\text{Zn}) = -0.76\,\text{V}\).\nCalculate the cell potential under these conditions using the Nernst equation and state whether the cell will operate spontaneously.

Answer Options

A. 1.05 V (spontaneous)
B. 1.20 V (spontaneous)
Correct Answer C. 1.13 V (spontaneous)
D. 0.78 V (non-spontaneous)
Correct Answer
C
Correct Option:
1.13 V (spontaneous)
