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 WebCarbon naturally exists as graphite and diamond. The enthalpy difference between graphite and diamond is too large for both to have a standard enthalpy of formation of zero. To determine which form is zero, the more stable form of carbon is chosen. how to sample in pro tools https://veritasevangelicalseminary.com
