Graphite combustion
WebGraphite is the most stable form of carbon under standard conditions. Therefore, it has a standard enthalpy of formation of zero, but of course, diamond also exists under standard conditions but it's not the most stable form. So its standard enthalpy formation is not zero, it's 1.88 kilojoules per mole.
