WebJun 17, 2024 · Isn't the enthalpy of formation the negative of enthalpy of combustion. No! That certainly isn't true. Consider this equation: $\ce{CH4 + O2 -> CO2 + H2O}$. If you reverse it, you'll get: $\ce{CO2 + H2O -> CH4 + O2}$ which is clearly not an enthalpy of formation because: the left hand side of the reaction does not have elements instead … WebApr 6, 2024 · The enthalpy of combustion of isooctane provides one of the necessary conversions. Table 6.4. 1 gives this value as −5460 kJ per 1 mole of isooctane (C 8 H 18 ). The combustion of 1.00 L of isooctane produces 33,100 kJ of heat. (This amount of energy is enough to melt 99.2 kg, or about 218 lbs, of ice.)
