The complete combustion of carbon compounds produces carbon dioxide. The reaction of coal with water at high temperatures produces synthesis gas, which is a mixture of carbon monoxide and hydrogen. Use the bond energies in the table below to estimate how much more energy is released by reaction I than by reaction II; that is, estimate HI - HII.
(I) C(g) + O2(g) CO2(g)
(II) C(g) + H2O(g) CO(g) + H2(g)
A) 470 kJ/mol
B) 770 kJ/mol
C) 275 kJ/mol
D) 575 kJ/mol
E) 1,045 kJ/mol
