At 20oC and 750 torr pressure, the mean free paths for argon gas (Ar) and nitrogen gas
Question:
At 20oC and 750 torr pressure, the mean free paths for argon gas (Ar) and nitrogen gas (N2) are λAr = 9.9 x 10-6 cm and λA2 = 27.5 x 10-6 cm.
(a) Find the ratio of the diameter of an Ar atom to that of an N2 molecule. What is the mean free path of argon at?
(b) 20oC and 150 torr, and
(c) – 40oC and 750 torr?
