Calculate E∘cell for each of the following balanced redox reactions.
Part a.
O2(g)+2H2O(l)+4Ag(s) → 4OH−(aq)+4Ag+(aq)
Part b.
Br2(l) + 2I−(aq) → 2Br−(aq) + I2(s)
Part c.
PbO2(s)+4H+(aq)+Sn(s)→Pb2+(aq)+2H2O(l)+Sn2+(aq)
Part d.
Which of the reactions are spontaneous as written.
Check all that apply
Br2(l)+2I−(aq)→2Br−(aq)+I2(s)
PbO2(s)+4H+(aq)+Sn(s)→Pb2+(aq)+H2O(l)+Sn2+(aq)
O2(g)+2H2O(l)+Ag(s)→4OH−(aq)+4Ag+(aq)
