59. Solving a chemistry problem

2. To the heat carried away by the flue gas at atmospheric pressure, if the composition of its components in volumetric percentage is known, the total gas volume, the temperature of the flue gas when exit from the T1 furnace and the ambient temperature T2, molar heat (J/(mol-k) components smoke gas within these temperatures are equal:
CP, CO2 = 44.44 9.04*10-3T-8.53*105T-2
CP, CO = 28.41 4.10*10-3T-0.46*105T-2
CP, O2 = 31.46 3.39*10-3T-3.77*105T-2
CP, N2 = 27.87 4.27*10-3T.
Take your option number from the table. 1
