Combustion of Octane (Gasoline)
2C8H18 + 25O2 → 16CO2 + 18H2O
Aperçu
Octane, a major component of gasoline, burns in oxygen to produce carbon dioxide and water. This reaction powers internal combustion engines in cars and is one of the most economically important chemical reactions. Isooctane (2,2,4-trimethylpentane) defines the 100 octane rating standard.
