Question

7. The standard electrode potentials for the half ceil
reactions are
Zn → Zn2+ + 2e E = + 0.76 V
Fe + Fe2+ + 2e E= + 0.41 V
The emf of the cell reaction Fe2+ + Zn → Zn2+ + Fe
(A)-0.35 V (B) +0.35 V (C)-1.17 V (D) + 1.17 V
​

Answer 1

Explanation:

Ecell = E cathode - Eanode

Ecell = -0.41 - 0.76 = -1.17 V
