Coal Gasification Can Be Represented by the Equation: 2 C(s)

question 100

Multiple Choice

Coal gasification can be represented by the equation: 2 C(s) + 2 H₂O(g) → CH₄(g) + CO₂(g) ΔH = ?
Use the following information to find ΔH for the reaction above.
CO(g) + H₂(g) → C(s) + H₂O(g) ΔH = -131 kJ
CO(g) + H₂O(g) → CO₂(g) + H₂(g) ΔH = -41 kJ
CO(g) + 3 H₂(g) → CH₄(g) + H₂O(g) ΔH = -206 kJ

• A)15 kJ
• B)116 kJ
• C)-116 kJ
• D)-372 kJ
