Chemistry - Real Gas Question with Solution | TestHub

0°C (273 K) is below the Boyle temperature of N₂ (≈ 332 K). At low pressure (large V) attractions dominate, Z < 1, so the real gas sits below the ideal curve; at high pressure (small V) repulsions dominate, Z > 1, so it sits above. The curves cross, with real above ideal at low V and ideal above real at high V: graph (d). Confirms Ans (d).
