Using the Following Data,calculate the Standard Enthalpy of Reaction for the Coal

question 22

Multiple Choice

Using the following data,calculate the standard enthalpy of reaction for the coal gasification process 2C(s) + 2H₂O(g) → CH₄(g) + CO₂(g) .
C(s) + H₂O(g) → CO(g) + H₂(g) ; ΔH° = +131.3 kJ
CO(g) + H₂O(g) → CO₂(g) + H₂(g) ; ΔH° = -41.2 kJ
CO(g) + 3H₂(g) → CH₄(g) + H₂O(g) ; ΔH° = -206.1 kJ

• A)-116.0 kJ
• B)378.6 kJ
• C)+15.3 kJ
• D)-157.2 kJ
• E)-378.6 kJ
