The relation between `E^0` and the equilibrium constant K is given by
Here, relevant `E^0` values are:
Ni(s) → Ni^(2+) +2e- (`E^0=0.25` V)
and Ag^+ + e- → Ag(s) (`E^0=0.80` V) *2
2Ag^+ + 2e- → 2Ag(s) (`E^0=0.80` V)
`E^0` (overall) = 0.80+0.25 = 1.05 V
Plugging in the valuesin the relation of K,
`rArr K =3.26*10^35`
Hence the value of equilibrium constant for the reaction between Ni(s) and `Ag^+` is `3.26*10^35` .
