For a stoichiometric amount of methane-air mixture calculate the mass fractions and stoichiometrically weighted mass fractions (with the fuel being the reference species and YF, B = 1) of O2 and CH4 before reaction, and of CO2 and H2O after complete reaction without dissociation. What can you say about Ỹ; and the small value of YCH relative to Yo₂ in terms of the suitability of hydrocarbons as transportation fuels?
