The mean free path of molecules of a gas (radius r) is inversely proportional to

A

` r ^(3)`

B

` r^(2)`

C

` r `

D

` sqrtr `

Text Solution

Verified by Experts

The correct Answer is:
B

Mean free path ` lambda _m = (1)/(sqrt2 pi d^(2) n) `
Where d= diameter of molecule ` rArr lambda_m prop (1)/( r^(2))`
