Chemistry - Real Gas Question with Solution | TestHub

For gases like N₂, O₂, CO₂, 0°C lies below the Boyle temperature. At low pressure (large V) attractions dominate, Z < 1, so the real gas pressure is below ideal; at high pressure (small V) repulsions dominate, Z > 1, so the real gas pressure is above ideal. The curves cross, with real above ideal at low V and ideal above real at high V: graph (d). Confirms Ans (d).
