At `20^(@)C` temperature, an argon gas at atmospheric pressure is confined in a vessel with a volume of `1 m^(3)` The effective hard spere diameter of argon atom is `3.10xx10^(-10)`m. determine mean free path.

A

100 nm

B

90 nm

C

93.6 nm

D

95 nm

Text Solution

Verified by Experts

The correct Answer is:
C
Mean free path,
`lambda=(kT)/(sqrt(2pi)rhod^(2)`
`lambda =(1.381xx10^(-23)(293))/(sqrt(2)pi(1.013xx10^(5))(3.10xx10^(-10)^(2)`
`lambda = 93.6 nm`
