The half-reactions in a nickel-cadmium (nicad) battery are: Cd(s)+2OH−(aq)Cd(OH)2(s)+2e− E°ox = 0.40 V
2NiO(OH)(s)+2H2O(l)+2e−2Ni(OH)2(s)+ 2OH−(aq) E°red = 1.32 V
Suppose a C battery has a capacity of 3.00 W·hr at an average voltage during discharge that is 70.0% of the standard cell potential. Answer the three questions below.
1. How much electrical energy in joules can the battery supply (in joules)?
2. How much electrical charge in ampere-hours can the battery deliver at the average discharge voltage (in A x hr)?
3. After complete discharge, how many moles of electrons have been transferred (in mol e-)?
