Gaseous state

Question

50 mL of H₂ gas diffuses through a small hole from a vessel in 20 min. Time taken by 40 mL of O₂ gas to diffuse under similar conditions will be

Moderate

A

12 min
B

64 min
C

8 min
D

32 min

Solution

$r (H_{2}) = \frac{50}{20} = 2 .5 r (O_{2}) = \frac{40}{t} \Rightarrow \frac{r (H_{2})}{r (O_{2})} = \frac{2 .5}{40 / t} = \sqrt{\frac{M (O_{2})}{M (H_{2})}} = \sqrt{\frac{32}{2}} = 4 2 .5 t = 160 ∴ t = 64 \min$
