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 the enthalpy of the reaction C(g) + H2O(g) ? CO(g) + H2(g) Energy(kj/mol) c-o = 358 c=o = 770 c-triple bond-o = 1070 o-h = 465 h-h = 435
