Question
Use these three reactions
CH4(g) + 2 O2(g) −→ CO2(g) + 2 H2O(g)
∆H◦ = −802 kJ
CH4(g) + CO2(g) −→ 2 CO(g) + 2 H2(g)
∆H◦ = 247 kJ
CH4(g) + H2O(g) −→ CO(g) + 3 H2(g)
∆H◦ = 206 kJ
to determine the appropriate enthalpy change of
CH4(g) + 3/2O2(g) −→ CO(g) + 2 H2O(g).
Choose the correct answer:
1. −200 kJ
2. −330 kJ
