Chemistry

1) Calculate the enthalpy of reaction(ΔHrxn) for the followingreaction:

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

Given: 4 Fe(s) + 3 O2(g) → 2 Fe2O3(s) ΔH = –1648 kJ 2CO2(g) → 2 CO(g) + O2(g) ΔH = +565.4 kJ

2) Use standard enthalpies of formation to calculate thestandard enthalpy of reaction for the followingreaction:

2 H2S(g) + 3 O2(g) → 2 H2O(l) + 2 SO2(g)ΔH∘rxn
