Problem

Two standard galvanic cells are constructed at 298 K. • Cell A transfers 1 mol e⁻ per reaction and has

E^{\circ}_{\text{cell}}=+0.45\,\text{V}

. • Cell B transfers 3 mol e⁻ per reaction and has

E^{\circ}_{\text{cell}}=+0.30\,\text{V}

. Which statement correctly compares the thermodynamic driving forces of the two cells under standard conditions? a) Cell A provides the larger driving force because it has the higher

E^{\circ}_{\text{cell}}

. b) Cell A provides the larger driving force because the product

nE^{\circ}_{\text{cell}}

(

0.45

) is greater than that of Cell B. c) Cell B provides the larger driving force because the product of the electron count and the cell potential is greater. d) Cell A provides the larger driving force because, on a per-electron basis, its potential is greater than that of Cell B.
