Step 1: The Concept
An electrochemical cell is made up of two half-cell compartments and carries out the conversion of the chemical energy of a spontaneous reaction into electrical energy.
Both half-cell compartments have a metal rod/stripe called the electrode, that is dipped in a suitable electrolytic solution.
Each electrode (anode or cathode) has a certain standard electrode potential that measures its ease of getting reduced.
The difference between the standard electrode potentials of the cathode and the anode is called the standard cell potential.
Step 2: The Approach
The relationships between the Gibbs free energy, the equilibrium constant, and the standard cell potential are given below:
