Solution: The overall reaction and standard cell potential at 25°C for the rechargeable nickel–cadmium alkaline battery isCd(s) + NiO2(s) + 2H2O(l) → Ni(OH)2(s) + Cd(OH)2(s)       E° = 1.10 VFor every mole of C

Problem

The overall reaction and standard cell potential at 25°C for the rechargeable nickel–cadmium alkaline battery is

Cd(s) + NiO2(s) + 2H2O(l) → Ni(OH)2(s) + Cd(OH)2(s)       E° = 1.10 V

For every mole of Cd consumed in the cell, what is the maximum useful work that can be obtained at standard conditions?
