WebThe definition of standard enthalpy of formation is the change in enthalpy when one mole of a substance is formed in its standard state from its constituent elements in their standard state at 298k and 1 atm. Since elements like Oxygen are in their standard state, there is no standard enthalpy of formation to talk about here.
