WebStandard enthalpy of combustion is defined as the enthalpy change when one mole of a compound is completely burnt in oxygen with all the reactants and products in their standard state under standard conditions (298K and 1 bar pressure). For example: H 2 ( g) + 1 2 O 2 ( g) → H 2 O ( l); Δ c H ° = − 286 k J m o l − 1.
