Questions about adiabatic flame temperature in combustion

Extracted text: Exercise about Adiabatic Flame Temperature Note: if initial temperature not know take it 298K. Q1: A one mole of Methane is burned at equivalence ratio (0.7), the fuel - air mixture at initial temperature 298K. After complete combustion. After complete combustion, determine (a) the mole fraction of production analysis. (b) the adiabatic flame temperature. Ans: XCO2=0.06849, xH;O=0.1369 , xN3=0.7358 ,xOz=0.0587 T.=1856.9K Q2: re-solution equation one but change the initial temperature of fresh gases to 323K. Ans: T=1877.6K Q3: Analysis of production gases for IC engine show that the mole fractions as: XCO2=0.08637, xH,O=0.1727,x02=0.01192, xN2=0.7217. Determine: (a) the equivalence ratio (b) the adiabatic flame temperature. Ans: D=0.9 , T,=2191.4K
