Which of the following will form a cell with highest voltage?
1M Ag+ , 1M Co2+
2M Ag+ , 2M Co2+
0.1M Ag+ , 2M Co2+
2MA Ag+ , 0.1M Co2+

Option D is correct.
The cell reaction is
From the equation,
Smaller the concentration of [Co2+] and larger the concentration of [Ag+] will produce maximum e.m.f.
So the correct option is D, 2 M Ag+ and 0.1 M Co2+.
