For a process of combustion of Butane (formation enthalpy= -332,000 kJ/kmol) C4H10O with an excess of 25% of air (Reactives are in standard conditions of T=25 C, P= 1 atm) 

Determine: A) The reason of air and fuel B) The reason of fuel and air C) The molar fractions of the product D) Temperature of the adiabatic flame E) If the products come out at a temperature of 600 K, determine de heat generated in the combustion chamber.
