Use Hess’s Law to determine the molar enthalpy of carbon monoxide when it reacts with hydrogen as shown below. 

4 CO(g)  +  8 H2(g)  →  3 CH4(g)  +  CO2(g)  +  2 H2O(l)4 CO(g)  +  8 H2(g)  →  3 CH4(g)  +  CO2(g)  +  2 H2O(l)C  +  ½ O2(g)  →  CO(g)   C  +  ½ O2(g)  →  CO(g)    ΔH°f  =  −110.5 kJ ΔH°f  =  -110.5 kJ 
CO(g)  +  ½ O2(g)  →  CO2(g)CO(g)  +  ½ O2(g)  →  CO2(g)ΔH°f  =  −282.9 kJ ΔH°f  =  -282.9 kJ
