Problem
Consider the following closed systems at constant temperature:
I. A sealed flask contains the interconversion N₂O₄(g) ⇌ 2 NO₂(g). The brown color intensity remains constant, and spectroscopy shows continuous formation and consumption of both species.
II. A rigid steel cylinder holds pure N₂(g) at constant pressure and no chemical reaction occurs.
Identify which system is in dynamic equilibrium and justify your choice in one to two sentences.
