5. Propane (C3H8) gas, supplied at 1atm and 298K, is burned adiabatically in a steady- flow burner with air supplied at the same pressure and temperature. Assume that the air flow is such that the combustible mixture is 10% richer (by volume) than the stoichiometric conditions. Case 1: Write the global chemical reaction equation to express the full utilization of fuel and air in the generation of combustion products under the assumption of no product dissociation Case 2: If the combustion products contain: CO2, H2O, CO, H2, O2 and N2; rewrite the global reaction equation to reflect the dissociation of CO2 and water vapour. Also, express the relationships between the moles of product species. a. Calculate the fuel/air mass ratio b. Calculate the adiabatic flame temperature for both cases and the equilibrium composition for the second case
