$E^{\circ}_{Cu^{2+}|Cu} = +0.34 \ V$
$E^{\circ}_{Zn^{2+}|Zn} = -0.76 \ V$
Identify the incorrect statement from the options below for the above cell.

  • A
    If $E_{\text{ext}} > 1.1 \ V$,$Zn$ dissolves at $Zn$ electrode and $Cu$ deposits at $Cu$ electrode.
  • B
    If $E_{\text{ext}} > 1.1 \ V$,$e^{-}$ flows from $Cu$ to $Zn$.
  • C
    If $E_{\text{ext}} = 1.1 \ V$,no flow of $e^{-}$ or current occurs.
  • D
    If $E_{\text{ext}} < 1.1 \ V$,$Zn$ dissolves at anode and $Cu$ deposits at cathode.
