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

Pick out the wrong unit conversion of heat transfer co-efficient.

1 W/m² . °C = 0.1761 BTU/ft².hr.°F

1 kcal/m².hr.°C = 0.2048 BTU/ft².hr. °F. = 1.163 W/m².°K

1 kcal/m².hr.°K = 1.163 W/m².°C

1 BTU/ft².hr.°F = 4.88 kcal/m².hr.°C = 20.44 kJ/m².hr°C = 5.678 W/m².°C
