Question : 41

Total: 100

For the cell Zn(s)|Zn2+(aq)|Mx+(aq)|M(s), different half cells and their standard electrode potentials are given below:

Mx+(aq)∕	Au3+(aq)	Ag+(aq)∕	Fe3+(aq)	Fe2+(aq)
M(s)	Au(s)	Ag(s)	Fe2+(aq)	Fe(s)
E∘Mx+∕M∕(V)	1.40	0.80	0.77	0.44

If EZn2+∕Zn2=−0.76V, which cathode will givea maximum value of E‌ecll ‌∘ per electron transferred?

[Jan. 11, 2019 (I)]

Ag+∕Ag
Fe3+∕Fe2+
Au3+∕Au
Fe2+∕Fe
