Question 957: Thermodynamics & KTG

Question

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

Accepted Answer

Mean free path $${\lambda _m} = {1 \over {\sqrt 2 \pi {d^2}n}}$$
where d = diameter of molecule and d = 2r
$$ 	herefore {\lambda _m} \propto {1 \over {{r^2}}}$$
