Starting with the standard free energies of formation from the following table, calculate the values of ΔG° and E°cell of the following reactions.

Substance ΔΔf (kJ/mol)
FeO(s) -255.2
H2(g) 0
Fe(s) 0
H2O(l) -237.2
Pb(s) 0
O2(g) 0
H2SO4(aq) -744.5
PbSO4(s) -813.0

1) FeO(s) +H2(g) ----Fe(s) +H2O(l)

change in G=18kj

E Cell= v

2) 2Pb(s)+O2(g)+2H2SO4(aq)--------2PbSO4(s)+2H2O(l)

change in G=-611.4

  cell =  blank.png V
