WebThe standard enthalpy of formation "The enthalpy of formation is the energy change when 1 mole of a substance is formed from its constituent elements in their standard states" Particular points to note: The elements are in their usual states under standard conditions. i.e at 25ºC and 1 atmosphere pressure (100.0 kPa). Web3.5.2.3 Heat of Formation. HF, also known as enthalpy of formation, is the enthalpy change when 1 mol of compound is formed at standard state (25°C, 1 atm) from its constituting elements in their standard state. For example, hydrogen and oxygen are stable in their elemental form, so their enthalpy of formation is zero.
