`Cu(s)|Cu^(+2)(aq,10^(-3))||Ag^(+)(10^(-5)M)|Ag(s)`
if `E_(Cu^(+2)//Cu=0.34V` ltBrgt `E_(Ag^(+)//Ag=+0.80V`
`E_("cell")` will be :-

A

`0.46 V`

B

`0.46-(RT)/(2F)ln 10^(7)`

C

`0.46+(RT)/(2F) ln 10^(7)`

D

`0.46+(RT)/(2F)ln 10^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`E_("cell")=0.85-0.34-(RT)/(2F)ln.((10^(-3)))/((10^(-5))^(2))`
`=0.46-(RT)/(2F)ln10^(7)`
