Problem Details

Calculate the maximum electrical work that can be produced by this cell.

3 Co 2+ (aq) + 2 Cr (s) 2 Cr 3+ (aq) + 3 Co (s)

Given the following reduction potentials:

Cr 3+ + 3 e –      →       Cr                      E ° = - 0.74 Volts 

Co 2+ (aq) + 2 e –       →       Co            E ° = - 0.28 Volts 

Faraday’s constant = 96,500 Coulombs / mole of electrons

a) – 800 kJ      b) – 150 kJ      c) – 266 kJ      d) + 266 kJ
