A cell reaction is written once as $Zn + Cu^{2 +} \to Zn^{2 +} + Cu$ and again with all coefficients doubled. For the doubled equation, compared with the first:

Options:

Answer:

Solution:

$E_{ce ll}^{\circ}$ is intensive and does not change with the way the equation is scaled. $Δ G^{\circ} = - n F E^{\circ}$ and $n$ doubles, so $Δ G^{\circ}$ doubles.
