Question 46 NECO • 2024 • CHEMISTRY • objective

Calculate the electromotive force (EMF) at 25 °C for a galvanic cell composed of a Zn electrode in a 0.010 M ZnSO\(_4\) solution and a Cu electrode in a 0.10 M CuSO\(_4\) solution. The standard reduction potentials are \(E^\circ_{\text{Zn}^{2+}/\text{Zn}} = -0.76\ \text{V}\) and \(E^\circ_{\text{Cu}^{2+}/\text{Cu}} = +0.34\ \text{V}\). Then determine the equilibrium constant \(K\) for the overall cell reaction at 25 °C.

Answer Options

Correct Answer A. E_{cell}=1.13 V; K≈1.4×10^{37}
B. E_{cell}=1.10 V; K≈5.0×10^{35}
C. E_{cell}=1.20 V; K≈3.2×10^{38}
D. E_{cell}=0.58 V; K≈2.5×10^{10}
Correct Answer
A
Correct Option:
E_{cell}=1.13 V; K≈1.4×10^{37}
