Question
The standard reduction potentials for Zn2+ / Zn, Ni2+ / Ni and Fe2+ / Fe are - 0.76, - 0.23 and - 0.44 V respectively. The reaction X + Y2+ → X2+ + Y will be spontaneous when
Options
A.X = Zn, Y = Ni
B.X = Ni, Y = Fe
C.X = Ni, Y = Zn
D.X = Fe, Y = Zn
Solution
X = Zn Y = Ni
= 0.76 - 0.23 = 0.53 V
Eocell = + ve
ᐃGo = - ve so spontaneous process
