Au/Cr cell will run as a voltaic cell and Co/Zn cell will run as an electrolytic cell.
<h3>What is an electrolytic cell?</h3>An electrolytic cell that uses electrical energy to enable a non-spontaneous redox reaction is known as an electrolytic cell.
Certain chemicals can be electrolyzed using electrolytic cells, which are electrochemical cells.
For example, water can be electrolyzed to create gaseous oxygen and gaseous hydrogen with the use of an electrolytic cell.
The following are the three essential parts of electrolytic cells:
Cathode (which is negatively charged for electrolytic cells)
Anode (which is positively charged for electrolytic cells)
Electrolyte
The reactions for each half cell is given by
; E° = 1.50 V
; E° = –0.74 V
; E° = –0.28 V
; E° = –0.76 V
When the Au/Cr cell will run as a voltaic cell and Co/Zn cell will run as an electrolytic cell, the a difference in the voltages is produced
= 2.24 V – 0.48 V = 1.76 V
