FREE Expert Solution

We are being asked to determine which reaction occurs at the cathode and which reaction occurs at the anode for a voltaic cell.

Recall:voltaic cell represents an electrochemical cell that is spontaneous

It has two half-cells, specifically, the anode and the cathode.

Each cell has a cell potential expressed by E or E°. (E° is the cell potential at standard conditions)

The greater the cell potential then the more likely reduction occurs. The smaller the cell potential then the more likely oxidation occurs. Reduction occurs at the cathode and oxidation occurs at the anode.
