What is the emf of a cell consisting of a pb2+ / pb half-cell and a pt / h+ / h2 half-cell if [pb2+] = 0.83 m, [h+] = 0.064 m and ph2 = 1.0 atm ?

The emf of the electrochemical cell has been calculated to be 0.0532 V.

The emf has been the potential of the cell in the reaction with the change in the electrons in the reaction. The emf of the cell has been given by the Nernst equation as;

The given cell has the number of electrons transfer,

The concentration of

The concentration of

The cell potential of the reaction has been,

Substituting the values for the emf of the cell:

The emf of the electrochemical cell has been calculated to be 0.0532 V.
