A Galvanic Cell Is Composed of These Two Half-Cells

Question 55

Multiple Choice

A galvanic cell is composed of these two half-cells: A galvanic cell is composed of these two half-cells:   The actual concentrations in the cell are: [Cu<sup>2+</sup>] = 0.00350 M, [Cr<sup>3+</sup>] = 0.360 M. What is the potential of this galvanic cell at 25°C?Hint: First calculate E°, then apply the solution concentrations of the galvanic cell using the Nernst equation. A) +1.06 V B) -0.16 V C) +1.02 V D) +1.14 V E) +1.98 V The actual concentrations in the cell are: [Cu2+] = 0.00350 M, [Cr3+] = 0.360 M.
