A galvanic cell consists of a metallic zinc plate immersed in 0.1 M Zn

1.	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. Calculte 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`)
Answer» Correct Answer - 0.6094V, `Zn+Pb^(2+)toZn^(2+)+Pb;Zn\|Zn^(2+)(0.1M)\|\|Pb^(2+)(0.02M)\|Pb`
