Calculate theoretical amount of air-combustion chamber

Question

Discuss the below:

Q: Using EES (or other) software, determine the rate of heat transfer for the fuels CH₄ (g), C₂H₂ (g), CH₃OH (g), C₃H₈ (g), and C₈H₁₈ (l) when they are burned completely in a steady-flow combustion chamber with the theoretical amount of air. Assume the reactants enter the combustion chamber at 298 K and the products leave at 1200 K.
