Use the following half-reactions to construct a voltaic cell:
cr3+(aq) + 3e−\rightarrow→ cr(s) eo = −0.73 v
ag+(aq) + e−\rightarrow→ ag(s) eo = 0.80 v
determine the balanced overall redox reaction, and calculate eocell.
3 ag(s) + cr3+(aq) \rightarrow→ 3 ag+(aq) + cr(s), eocell = −1.53 v
3 ag+(aq) + cr(s) \rightarrow→ 3 ag(s) + cr3+(aq),eocell = +3.13 v
3 ag(s) + cr3+(aq) \rightarrow → 3 ag+(aq) + cr(s), eocell = −3.13 v
ag(s) + cr3+(aq) \rightarrow→ ag+(aq) + cr(s), eocell = −1.53 v
3 ag+(aq) + cr(s) \rightarrow→ 3 ag(s) + cr3+(aq), eocell = +1.53 v
ag+(aq) + cr(s) \rightarrow→ ag(s) + cr3+(aq), eocell = +1.53 v
