Problem

Two reactions occur under standard conditions: Reaction X:

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

with

n = 2

electrons transferred. Reaction Y:

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

with

n = 4

electrons transferred. Which reaction is more thermodynamically favorable, or are they equally favorable? Give a brief justification based on the relationship between

\Delta G^\circ

and

E^\circ_{\text{cell}}
