Mean free path

Question

The mean free path of a molecule of a gas depends

Easy

A

only on its diameter, d
B

only on the number density (number of molecules per unit volume) of the molecules, n
C

d and n
D

neither d nor n

Solution

Mean free path, $λ = \frac{1}{\sqrt{2 π} d^{2} n}$
So, $λ$ depends on ‘d’ and ‘n’.
