A galvanic cell consists of a metallic zinc plate immersed in 0.1 M `Zn (NO_(3))_(2)` solution and metallic plate of lead in 0.02M `Pb(NO_(3))_(2)` solution. Calculate the emf of the cell.
Write the chemical equation for the electrode reactions and represent the cell.
`("Given" : E^(@) Zn^(2+)ZN=-0.76V, "
" E^(@)Pb^(2+)//Pb = -0.13V)`
