Which of the following equations does NOT show incomplete
combustion?
Response options group
CH4 (g) + 1.75O2 (g) ----> 0.5 CO (g) + 0.5 CO2 (g) + 2 H2O (v)
CS2 (g) + 2.75 O2 (g) ----> CO2 (g) + 0.5 SO3 (g) + 1.5SO2 (g)
SO2 (g) + 0.5 O2 (g) ----> SO3 (g)
2FeS2 (s) + 5.5O2 (g) ---> Fe2O3 (s) + 4SO2 (g)
Homework Answers
Option 3
SO2 + 0.5 O2 = SO3 represent complete combustion of SO2.
All other reactions have limited combustion yield. As other reactions do not proceed to completion due to kinetics constraints. All other products SO2,CO relatively unstable except SO3. The formation of unstable CO, SO2 is represent incomplete combustion of reactants in reaction 1, reaction 2 and reaction 4. But the formation of SO3 (more stable ) from relatively unstable SO2 is represent completion of reaction.
