Alkanes as Fuel
Alkanes are widely used as fuels because combustion is exothermic and releases useful energy. These pages separate the fuel topic into combustion chemistry, pollutant formation and catalytic converter treatment so students can connect equations, reaction conditions and environmental consequences.
Revision Notes
Work through each part of Edexcel Topic 6 in a structured sequence.
Combustion
Revise complete and incomplete combustion of alkanes, including the key products, equations and why combustion releases energy.
Start revisingOxides of Sulfur
Learn how sulfur impurities in fuels form sulfur dioxide and how sulfur oxides contribute to acid rain and environmental damage.
Start revisingOxides of Nitrogen
Review how high temperatures in engines allow nitrogen and oxygen from air to react, producing nitrogen oxides that cause pollution.
Start revisingCatalytic Converter
Revise how catalytic converters use transition metal catalysts to convert harmful exhaust gases into less harmful products.
