A galvanic cell consists of a metallic zinc plate immersed in 0.1 M Zn(NO3)2 solution and metallic plate of lead in 0.02 M Pb(NO3)2 solution. Calculate the emf of the cell. Write the chemical equation for the electrode reactions and represent the cell.
(Given : E°Zn2+/Zn = -0.76 V; E°Pb2+/Pb = -0.13 V)
