Metallurgical Engineering > GATE 2020 > Galvanic Cell
A galvanic cell is formed by connecting Zn (EoZn2+/Zn = -0.76 V) and Fe (EoFe2+/Fe = -0.44 V) wires immersed in their respective ion solutions. The cell discharges spontaneously with a voltage of 0.5 V. The ratio of the concentration of [Fe2+] to [Zn2+] ions in the cell is of the order of:
Given, R = 8.314 J⋅mol-1⋅K-1, F = 96500 C⋅mol-1, T = 298 K
Given, R = 8.314 J⋅mol-1⋅K-1, F = 96500 C⋅mol-1, T = 298 K
Correct : c
