Question

When propane gas (C3H8, used for gas barbecue) combusts in air, several different products can form based on how much oxygen is available. Consider each statement below and choose the best response.

A.When a plentiful supply of O2 is present, the reaction that occurs is C3H8 + 5O2 3CO2 + 4H2O.

B.When some, but not enough, O2 is present, the reaction that occurs is C3H8 + 3O2 3CO2 + 4H2.

C.When just enough O2 is present (a stoichiometric amount), the reaction that occurs is C3H8 + O2 CH3COOH (acetic acid) + CH4 (methane).

D.When too little O2 is present, the reaction that occurs is 2C3H8 + O2 2C3H7OH (rubbing alcohol).

Explanation / Answer

A.When a plentiful supply of O2 is present, the reaction that occurs is C3H8 + 5O2 3CO2 + 4H2O.

propane combustion in presence of excess of oxygen to form CO2 and H2O.
