Question: what is the standard enthalpy of combustion?
Answer: Standard enthalpy of combustion (ΔH∘C Δ H C ∘ ) is the enthalpy change when 1 mole of a substance burns (combines vigorously with oxygen) under standard state conditions; it is sometimes called “heat of combustion.” For example, the enthalpy of combustion of ethanol, −1366.8 kJ/mol, is the amount of heat produced when ...
