Select the correct statement(s) for the given relation
`Cu(s)+2Ag^(+)(aq)rarrCu^(2+)(aq)+2Ag(s)`

Options

A. Reaction at cathode ,`Cu(s) rarr Cu^(2+) (aq) +2e^(-)`
B. `E_(Cell)=E_(cu^(2+)//Cu) -E_(Ag^(+)//Ag)`
C. Cell reaction is,
`Cu(s)|Cu^(2+)(aq)||Ag^(+)(aq)|Ag(s)`
D. None of the above

Answer

C

Explanation

Cell reaction
`Cu (s) +2 Ag^(+) (aq) rarr Cu^(2+) (aq)+2Ag(s)`
`Cu(s)|Cu^(2+) (aq)||Ag^(+) (aq)|Ag(s)`
`E_("cell")=e_("right")-E_("left")=E_(Ag^(+)|Ag)-E_(Cu^(2+)|Cu)`
