The stoichiometric combustion of propane (C3H3) and air is given by the balanced expression C;Hg + 5 O2 + 18.8 N2 → 3 CO, + 4 H2O + 18.8 N, Part (a) – Write a balanced expression for combustion of propane in air for an equivalence ratio ø=0.85. Part (b) - Determine the lower heating value of propane expressed in terms of kJ/kg-propane. Part (c) For the conditions ø= 0.85, will the adiabatic flame temperature be higher or lower than 2100 K? Perform calculations to justify your answer.
