question

Ethane reacts with astoichiometricamount of air by the followingcombustion equation : C_2H_6 + 3.5O_2 + 3.5(3.76)N_2\rightharpoonup 2CO_2 + 3H_2O + 3.5(3.76)N_2. Using the following enthalpy data, calculate the amount of heattransfer per mole of fuel if ethane enters at 60 C, the air entersat 4.4°C and the products leave at 449°C.
