    By definition the standard enthalpy of formation of an element is 0.

    So does that mean any element by itself eg Carbon would have an enthalpy of formation of 0?

    definition of standard enthalpy change of formation:

    "enthalpy change when one mole of the compound is formed from its consituent elements under standard conditions. All products and reactants are in their standard states"

    N is N2(g) is in its standard state so the eqn would like this:
    N2(g) => N2(g)
    hence enthalpy change is 0.
