Which defines the standard reduction electrode potential of Zn^(2+) ions

Answer»

`Zn^(2+) (aq) + 2 E^(-)to Zn(s) , [Zn^(2+)] = 1 M`
`Zn(G) to Zn^(2+) + 2E^(-) , [Zn^(2+)] = 1 M`
`Zn^(2+) (aq) to Zn(s) + 2e^(-) , [ Zn^(2+)] = 1 M`
`Zn^(2+) (g) + 2 e^(-)to Zn(s) - 2e^(-), [Zn^(2+)] = 1 M`

Solution :`E^(@) = E ` , when `[Zn^(2+)] = 1M`,
Also process is `Zn^(2+) (aq)+ 2e to Zn(s)`
