The decomposition of nitrogen trifluoride (NF₃) is a highly endothermic reaction and requires a significant amount of energy to occur. It typically doesn't happen spontaneously under normal conditions. Here's the equation:

2 NF₃(g) → N₂(g) + 3 F₂(g)

Explanation:

* NF₃(g) represents nitrogen trifluoride in the gaseous state.

* N₂(g) represents nitrogen gas in the gaseous state.

* F₂(g) represents fluorine gas in the gaseous state.

Important Notes:

* This reaction requires high temperatures or specific catalysts to initiate the decomposition.

* The decomposition products, nitrogen and fluorine, are both highly reactive and potentially dangerous.
