Answer: C) 0.637 V
Explanation:
The balanced redox reaction is:
Here Zn undergoes oxidation by loss of electrons, thus act as anode. Lead undergoes reduction by gain of electrons and thus act as cathode.
Where both
are standard reduction potentials.
= -0.763
= -0.126
The standard emf of a cell is 0.637 V
