Consider the galvanic cell: Zn(s) | Zn^{2+}(0.10\ \text{M}) || Cu^{2+}(0.010\ \text{M}) | Cu(s) at 298 K. The standard reduction potentials are \(E^{\circ}_{\text{Cu}^{2+}/\text{Cu}} = +0.34\ \text{V}\) and \(E^{\circ}_{\text{Zn}^{2+}/\text{Zn}} = -0.76\ \text{V}\). (i) Calculate the cell potential \(E_{\text{cell}}\) under the given conditions using the Nernst equation. (ii) State whether the cell reaction is spontaneous.

Answer Options

A. E_{cell} = 0.85 V (spontaneous)
B. E_{cell} = 1.07 V (non-spontaneous)
Correct Answer C. E_{cell} = 1.07 V (spontaneous)
D. E_{cell} = 0.50 V (spontaneous)
Correct Answer
C
Correct Option:
E_{cell} = 1.07 V (spontaneous)
