Problem

Reactions X, Y, and Z each have the same standard cell potential,

E^{\circ}_{\text{cell}}=+0.50\,\text{V}

, but differ in the number of electrons transferred: X:

n=1

n=2

n=4

Which ranking correctly orders the reactions from most negative

\Delta G^{\circ}

(greatest thermodynamic driving force) to least negative

\Delta G^{\circ}

? a)

X > Y > Z

Y > Z > X

Z > Y > X

Y > X > Z
