Methane is burned with 20% excess air; both methane and air being at 298 K. The standard heat of combustion of methane at 298 K is – 802.625 kJ. The heat capacities in J/mol K are: Cp (CH4) = 14.150 +75.499 □ 10-³T– 17.9915 | 10–6 7² Cp(O2)=30.255+4.207 L 10-3T– 1.8873 L 105T-2 Cp(N2)=27.270+4.930 L 10-3T+3.3256 L 104T-2 Cp (CO2)=45.369 +8.688 L] 10-3T+9.6193 L 105T-2 Cp (H₂O) = 28.850 +12.055 □ 10-³T+1.006 105T-2 Calculate the adiabatic flame temperature attained.
