Question

Solve this:

35 The emf of a galvanic cell constituted with the electrodes Zn 2
+   Zn   - 0 76   V   and   Fe 2 +  
Fe - 0 41   V is
(1) -0 35 V (2) +1 17 V
(3) +0 35V (4) -1 17 V

Siva Sekhar B R · Accepted Answer

Zn is more reactive than Fe in series so Zn act as anode and Fe act
as cathode
Ecell= -0 41-(-0 76)
= +0 35V

Solve this: 35. The emf of a galvanic cell constituted with the electrodes Zn 2 + Zn - 0 . 76 V and Fe 2 + Fe - 0 . 41 V is (1) -0.35 V (2) +1.17 V (3) +0.35V (4) -1.17 V

Solve this:

35. The emf of a galvanic cell constituted with the electrodes ${Zn}^{2 +} |Zn (- 0.76 V) and {Fe}^{2 +}| Fe (- 0.41 V)$ is
(1) -0.35 V (2) +1.17 V
(3) +0.35V (4) -1.17 V
