Consider a fuel which is an equimolar mixture of propane (C3H8) and natural gas (CH4).

Consider a fuel which is an equimolar mixture of propane (C3H8) and natural gas (CH4). Write out the complete stoichiometric combustion reaction for this fuel burning with air and determine the stoichiometric fuel-air ratio on a molar basis. Also, determine the molar air-fuel ration for combustion at an equivalence ratio, of 0.8.
