6. As an alternative to combustion of coal gas described earlier in this section, coal gas can undergo a process called methanation. [3] 3 H₂(g) + CO(g) → CH4 + H₂O Determine the enthalpy change involved in the reaction of 300 g of carbon monoxide in this methanation reaction, using the following reference equation and enthalpy changes. (1) 2 H₂ + O₂ → 2 H₂O (2) 2 C+0₂ → 2CO (3) CH4 + 2 O₂ CO₂ + 2 H₂O CO₂ (4) C + O₂ AH= ? AH*₁= - 483.6 kJ AH*2= -221.0 kJ ΔΗ°3= -802.7 kJ AH*4= -393.5 kJ
