Calculate the thermal effect of the reduction reaction of ferrous (II) oxide with hydrogen based on the following thermochemical equations: FeO (solid) + CO (gas) = ​​Fe (solid) + CO2 (gas); ΔH = -13.18 kJ. CO (gas) + 0.5O2 (gas) = ​​CO2 (gas); ΔH = -283.0 kJ. H2 (gas) + 0.5O2 (gas) = ​​H2O (g); ΔH = -241.83 kJ
