Problem

Three standard reactions, each spontaneous under standard conditions, are shown below. Reaction A:

n=1

E^{\circ}_{\text{cell}}=+0.98\,\text{V}

Reaction B:

n=2

E^{\circ}_{\text{cell}}=+0.55\,\text{V}

Reaction C:

n=3

E^{\circ}_{\text{cell}}=+0.40\,\text{V}

Which reaction has the smallest magnitude of

\Delta G^{\circ}

(i.e., is least strongly driven toward products) at 298 K? a) Reaction C b) Reaction B c) Reaction A d) All three reactions have identical magnitudes of

\Delta G^{\circ}
