Step 1
Given
The concentration of Zn2+ is 1.0 M.
The pressure of H2 is 1 atm.
The reduction potential of Zn2+ is -0.76 V.
The potential of cell is 0.45 V.
Step 2
The Nernst equation is given as shown below.
Here, Ecell is the potential of cell in volts, E cell is the standard potential of the cell in volts, R is the universal gas constant 8.314 J K-1 mol-1, T is the temperature, n is the number of moles of electrons that are transferred, F is the Faraday’s constant 96500 C/mol e-, Q is the reaction quotient.
Step 3
Reaction taking place at the cathode is,
Reaction taking place at the anode is,
Step 4
Add both the equations.
The standard potential of cell is given as shown below.
