Statement 1: Graham's law of diffusion holds exactly for all real gases even at high pressures.
Statement 2: Real gases approach ideal behaviour, to which Graham's law strictly applies, only at low pressures.
Options:
Answer:
D
Solution:
Statement I is incorrect: at high pressure real-gas deviations (finite molecular volume, attractions) distort diffusion rates, so Graham's law is only approximate there. Statement II is correct: ideality is approached as P 0, which is why Graham's law is a limiting law used best at low pressure. Ans: (d).
