What is standard enthalpy?
The standard enthalpy of formation is the measurement of energy that is used or released in the formation of one mole of a substance from a pure element in its pure state. The standard enthalpy is denoted by ΔH°f.
Nitrogen is an important element of the living body. It is present in the highest amount in the atmosphere. In the following compounds. Only dinitrogen, N2 is a single element. So its ΔH°f = 0 kJ/mol
Thus, the correct option is D. N2(g).
