Consider a galvanic cell constructed as \(\mathrm{Zn|Zn^{2+}(0.010\;M)\;||\;Cu^{2+}(0.10\;M)|Cu}\). The standard reduction potentials are \(E^{\circ}(\mathrm{Zn^{2+}/Zn}) = -0.76\;\text{V}\) and \(E^{\circ}(\mathrm{Cu^{2+}/Cu}) = +0.34\;\text{V}\). (a) Calculate the cell potential at 25 °C using the Nernst equation. (b) Identify the anode and cathode. (c) Determine the equilibrium constant \(K\) for the overall cell reaction.

Answer Options

Correct Answer A. Ecell ≈ 1.13 V; anode = Zn electrode, cathode = Cu electrode; K ≈ 1.5 × 10^{37}
B. Ecell ≈ 0.58 V; anode = Cu electrode, cathode = Zn electrode; K ≈ 2.0 × 10^{10}
C. Ecell ≈ 1.13 V; anode = Cu electrode, cathode = Zn electrode; K ≈ 1.5 × 10^{37}
D. Ecell ≈ 1.10 V; anode = Zn electrode, cathode = Cu electrode; K ≈ 3.0 × 10^{35}
Correct Answer
A
Correct Option:
Ecell ≈ 1.13 V; anode = Zn electrode, cathode = Cu electrode; K ≈ 1.5 × 10^{37}
