Alkane Combustion

?

Reactions of Alkanes

Combustion: exothermic:

  • Alkane(g) + O2 (g) --> CO2(g) + H2O (g). 
  • Blue flame - bunsen burner complete combustion of methane

Incomplete combustion: 

  •  Alakane(g) + O2(g) --> CO(g)/C(s) + H2O(g).
  • Occurs if not enough O2 present.                    
  • Bunson yellow flame - incomplete combustion methane + oxygen as carbon impurities

Problems

- Car engine: incomplete combustion occurs --> green house gases, C0 posinours

-Petrol burns at very large temp - enough energy for nitrogen to react with oxygen 

  • N2(g) + O2(g) -->
