Reaction rate, 2 of 2. Charcoal consists of mostly carbon (C) and is typically obtained from wood by pyrolysis. Charcoal briquette burns fairly slowly in air (Photo 1). In this combustion reaction carbon dioxide is produced: C + O2 -> CO2. The rate of the reaction is limited by the concentration of oxygen (O2) in the air, about 20%. When a stream of pure oxygen is blown on burning charcoal through a nozzle (Photo 2), the reaction rate increases dramatically. | |
