For 2NO₂(g) ⇌ N₂O₄(g), what happens when the container volume is halved?
A.The reaction shifts toward N₂O₄
B.The reaction shifts toward NO₂
C.Nothing changes
D.K increases
Explanation
Core Concept
Compression raises pressure, so the system shifts toward fewer gas moles (1 vs 2), forming more N₂O₄. Fewer particles means lower pressure.
Correct Answer
AThe reaction shifts toward N₂O₄
