Interpretation:
The value of Gibb’s free energy for given cell reaction has to be calculated.
Concept introduction:
Standard reduction potential: The voltage associated with a reduction reaction at an electrode when all solutes are 1M and all gases are at 1 atm. The hydrogen electrode is called the standard hydrogen electrode (SHE).
Standard emf: Eocell is composed of a contribution from the anode and a contribution from the cathode is given by,
Where both
The change in free-energy represents the maximum amount of useful work that can be obtained in a reaction:
