It is interesting to compare the "fuel value" of a hydrocarbon in a hypothetical world where oxygen is not the combustion agent. The enthalpy of formation of CF4(g) is -679.9 kJ/mol.
Which of the following two reactions is the more exothermic?
CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)
CH4(g) + 4F2(g) → CF4(g) + 4HF(g)
