Assume that a vehicle engine combusts rubbing alcohol (C3H7OH).

a) Write a balanced chemical combustion equation for complete (stoichiometric) combustion with no excess air, and find the air-to-fuel ratio (in lbs air/lbs fuel) assuming air is 79% N2 and 21% O2 by volume. Assume the only products of combustion are water and carbon dioxide.

b) Assuming that one fourth of one percent (0.25%) of the carbon atoms in the fuel form CO instead of CO2, but that the amount of combustion air does not change, redo the combustion equation and calculate the concentration of CO in the exhaust gas in ppm (wet basis).
