Estimate the theoretical flame temperature of a gas containing 40% CO and 60% N2 when burned with 20% excess air. Both air and gas are initially at 25oC.
Cp CO2 = 6.339 + 10.14 x 10-3 T – 3.415 x 10-6 T
2
Cp O2 = 6.117 + 3.167 x 10-3 T - 1.005 x 10-6 T
2


Cp N2 = 6.457 + 1.389 x 10-3 T - 0.069 x 10-6 T
2
The values of Cp are in kcal/k mole K and temperature is in K
Hrxn 25oC = - 67636 kcal/k mole of CO2
