Solve this:
Q.5. Four rubber tubes are respectively filled with $H_2, O_2, N_2 and C{O}_2$. The tube which will be reinflated first is :
(1) $H_2$ filled tube
(2) $O_2$ filled tube
(3) $N_2$ filled tube
(4) $C{O}_2$ filled tube

Dear student,
According to Graham's Law of Effusion and Diffusion,
Rate of effusion or diffusion is inversely proportional to square root of molecular mass of corresponding gas.
It means, the lighter gas will be reinflated faster as compared to rest of the gases. In the above case, H₂ is the lightest gas hence it will be reinflated first.

Correct option is (1)

Hope it helps
