SUMMARY
The discussion focuses on the thermodynamic properties of the reaction N2(g) → 2N(g), specifically the signs of ΔH, ΔG, and ΔS. It is established that the reaction involves the dissociation of molecular nitrogen into atomic nitrogen, which is an endothermic process, indicating a positive ΔH. The reaction's spontaneity is questioned, leading to the conclusion that ΔG is also positive under standard conditions, reflecting non-spontaneity. Additionally, the increase in entropy due to the formation of two moles of gaseous nitrogen atoms from one mole of nitrogen gas results in a positive ΔS.
