Consider the galvanic cell `Cu|Cu^(2+)(0.13M)||Ag^(+)(0.01M)|Ag` (i) Calculate the reduction potential of each electrode and EMF of the cell
(ii) Is is reaction representing the cell spontaneous ?
`["Given : "E_(Cu^(2+)|Cu)^(@)=+0.34V and E_(Ag^(+)|Ag)^(@)=+0.80V]`

Explanation

Anode Reaction : `Cu(s)rarr Cu^(2+)(aq)+2e`
Cathode Reaction : `Ag^(+)(aq)+e rarr Ag(s)`
Anode reduction potential,
`E_(Cu^(2+)|Cu)^(@)=E_(Cu^(2+)|Cu)^(@)-(0.059)/(2)log.(1)/([Cu^(2+)])`
`=+0.34+(0.059)/(2)log0.13=+0.3138V`
