(a)
Interpretation:
The standard reduction potential of given cell has to be determined.
Concept introduction:
When the potentiometer is replaced with a wire in a cell there would be more current flows and concentration varies until the cell attains equilibrium. At this situation there is nothing to drive reaction. The cell voltage becomes zero.
