Strategy:
 Relate standard electrode potentials to standard Gibbs free energy (). Combine two known half-reactions to find the potential of the target half-reaction.

Step 1: Write known half-reactions and energies
1. : , 
 
2. : ,

Step 2: Define target reaction
Target: 
This is obtained by: .

Step 3: Solve for 
For target :
