WebFor an element the standard state is the form in which the element exists (is more stable) under condition of 1 bar and at the temperature of interest (usually 25°C). ΔH0f for an element in its standard state is zero. Thus, elements in their standard states are not included in the ΔH reaction calculations. Note! WebJun 13, 2024 · For any substance at any particular temperature, we define the standard enthalpy of formation as the enthalpy change for a reaction in which the product is one mole of the substance and the reactants are the compound’s constituent elements in their standard states. For water at –10 C, this reaction is. H2(g, − 10 C, 1 bar) + 1 2 O2(g, − ...
