Complete combustion of butanol (4 points): CH100 + 602 – 4CO2 + 5H20 b. Incomplete combustion of butanol (4 points): CAH100 + 402 – 4CO + 5H20 c. Which reaction releases more energy (1 point)?

The Difference Between Complete and Incomplete Combustion: Calculating Change in Bond Enthalpy

In terms of understanding the difference between complete and incomplete combustion, it is important to understand the concept of bond enthalpy. Bond enthalpy is defined as “the amount of energy required to break one mole of bonds of a given kind” (“Bond enthalpy”). This energy is released when the bonds are formed, and the difference between the amount of energy released and the amount needed to break the bonds is the change in bond enthalpy (Lubin, 2019). Calculating the change in bond enthalpy for a given reaction can help understand the differences between complete and incomplete combustion. For example, the complete combustion of butanol (CH100 + 602 – 4CO2 + 5H20) releases more energy than the incomplete combustion of butanol (CAH100 + 402 – 4CO + 5H20). This can be seen by calculating the change in bond enthalpy for each reaction. For the complete combustion of butanol, the energy released is (4×803 + 5×467) – (2×416 + 2×356 + 6×336 + 2×498) = 9,898 kJ, whereas for the incomplete combustion of butanol, the energy released is (4×803 + 5×467) – (2×416 + 2×356 + 4×336 + 2×498) = 8,932 kJ. Therefore, the complete combustion of butanol releases more energy than the incomplete combustion of butanol (Lubin, 2019). Cont…
