A galvanic cell is assembled with the half‑cells Cu²⁺/Cu(s) (E° = +0.34 V) and Fe²⁺/Fe(s) (E° = -0.44 V). The concentrations are [Cu²⁺] = 0.010 M and [Fe²⁺] = 0.10 M at 25 °C. Calculate the cell potential (Ecell) and indicate which electrode functions as the cathode.

Answer Options

A. Ecell = 0.880 V; cathode = Cu²⁺\/Cu electrode
B. Ecell = 0.750 V; cathode = Fe²⁺\/Fe electrode
C. Ecell = 0.620 V; cathode = Fe²⁺\/Fe electrode
Correct Answer D. Ecell = 0.750 V; cathode = Cu²⁺/Cu electrode
Correct Answer
D
Correct Option:
Ecell = 0.750 V; cathode = Cu²⁺/Cu electrode
