Question

Coal gasification can be represented by the equation:
2 C(s) + 2 H2O(g) -> CH4(g) + CO2(g) H = ?
Use the following information to find H for the reaction above.
CO(g) + H2(g) -> C(s) + H2O(g) H = -131 kJ
CO(g) + H2O(g) -> CO2(g) + H2(g) H = -41 kJ
CO(g) + 3 H2(g) -> CH4(g) + H2O(g) H = -206 kJ
A) 15 kJ
B) 116 kJ
C) -116 kJ
D) -372 kJ
