Critical temperatures of H₂, N₂ and NH₃ are 33 K, 126 K and 405 K, respectively. Which gas is more close to ideal behaviour at 400 K?
Options:
Answer:
D
Solution:
A gas approaches ideal behaviour the farther its temperature is above its critical temperature. At 400 K: H₂ has T/TC = 400/33 ≈ 12, N₂ has 400/126 ≈ 3.2, while NH₃ (405 K) is below its critical temperature. H₂ is farthest above its TC, hence closest to ideal. Ans: (d)
