Stoichiometry
Pick out the wrong unit conversion of calorific value.

1 kcal/m³ = 0.1124 BTU/ft³
1 BTU/lb = 2.3 kcal/kg
1 BTU/ft³ = 8.9 kcal/m³ = 0.038 MJ/m³
1 kcal/kg = 1.8 BTU/lb = 4.186 kJ/kg

Stoichiometry
One mole of methane undergoes complete combustion in a stoichiometric amount of air. The reaction proceeds as CH₄ + 2O₂ → CO₂ + 2H₂O. Both the reactants and products are in gas phase. ΔH°298 = - 730 kJ/mole of methane. If the average specific heat of all the gases/vapour is 40 J/mole.K, the maximum temperature rise of the exhaust gases in °C would be approximately equal to

1525
1735
1225
1335
