At `20^(@)` C, the standard oxidation potential of Zn and Ag in water are:
`Zn(s)rarr Zn^(2+) (aq) + 2e^(-), E^(o) = 0.76V`,
`Ag(s) rarr Ag^(+)(aq) + E^(-) , E^(o) = - 0.80 V`
The standard EMF of the given reaction is:
`Zn+2Ag^(+)rarr 2AG+Zn^(+2)`

A

`Zn^(2oplus) (aq) rArr Ag^(oplus) (aq) rArr Zn(s) + Ag(s)`

B

`Zn(s) + 2Ag(s) rArr Zn^(2oplus) (aq) + 2Ag^(+)(aq)`

C

`Zn(s) + 2Ag^(oplus) rArr Zn^(2) (aq) + 2Ag(s)`
