In the following reactions, label the oxidizing agent and the reducing agent.

a. Fe₂O₃ ( s ) + 3CO(g) → 2 Fe(s) + 3CO₂(g)

b. PbS(s) + 4H₂O₂ (aq) → PbSO₄ (s) + 4H₂O(l)

Part A

Calculate ÎHrxn for the following reaction:
Fe2O3(s)+3CO(g)â2Fe(s)+3CO2(g)
Use the following reactions and given ÎHâ²s.
2Fe(s)+3/2O2(g)âFe2O3(s), ÎH = -824.2 kJ
CO(g)+1/2O2(g)âCO2(g), ÎH = -282.7 kJ

Use data from Appendix IIB to calculate ?S?rxn for each of the reactions given below.

Cr2O3(s)+3CO(g)---->2Cr(s)+3CO2(g)

SO2(g)+1/2O2(g)----->SO3(g)

N2O4(g)+4H2(g)----->N2(g)+4H2O(g)
