Longest mean free path stands for

A

`H_(2)`

B

`N_(2)`

C

`O_(2)`

D

`Cl_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
The mean free path , `lambda=(1)/(sqrt(2)pi sigma^(2)N) `or `lambda prop (1)/(a^(2))`,
where ` a=` molecular diameter
`:. `Smaller the molecular diameter, longest the mean free path
Hence, `H_(2)` is the answer.
