Incomplete Combustion of Methane

2CH4 + 3O2 → 2CO + 4H2O

Overview

When methane burns in insufficient oxygen, carbon monoxide forms instead of carbon dioxide. This incomplete combustion is dangerous because CO is a toxic, odorless gas. Poorly ventilated gas appliances can produce CO, leading to carbon monoxide poisoning.

Participants

Role Substance Coefficient State
Reactant Methane CH₄ 2 (g)
Reactant Oxygen O 3 (g)
Product Carbon Monoxide CO 2 (g)
Product Water H₂O 4 (l)

Everyday Example

Carbon monoxide detectors in homes protect against this reaction occurring in gas furnaces, water heaters, and stoves with poor ventilation.

Industrial Importance

Steam reforming of methane (controlled incomplete combustion) is the primary industrial method for hydrogen production, producing syngas (CO + H2).
