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

Mx+ (aq) / M(s)	Au3+ (aq) / Ag (s)	Ag+ (aq) / Ag (s)	Fe3+ (aq) / Fe2+ (s)	Fe2+ (aq) / Fe (s)
E°Mx+∕M(v)	1.40	0.80	0.77	- 0.44

If E°Zn2+∕Zn = - 0.76 V , which cathode will give amaximum value of E°cell per electron transferred ?
