The Complete Combustion of Carbon Compounds Produces Carbon Dioxide Δ\Delta HI -

Question 103

Multiple Choice

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 Δ\Delta HI - Δ\Delta HII.
(I) C(g) + O2(g) \rightarrow CO2(g)
(II) C(g) + H2O(g) \rightarrow CO(g) + H2(g)  Bond OCCOHHH==OOO Energy (kJ/mol) 4957701,070465435\begin{array} { | l | c | c | c | c | c | } \hline \text { Bond } & \mathrm { O } & \mathrm { C } & \mathrm { C } & \mathrm { O } - \mathrm { H } & \mathrm { H } - \mathrm { H } \\& = & = & \equiv & & \\& \mathrm { O } & \mathrm { O } & \mathrm { O } & & \\\hline \text { Energy } ( \mathrm { kJ } / \mathrm { mol } ) & 495 & 770 & 1,070 & 465 & 435 \\\hline\end{array}
