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

Question

Vimal Swarnkar · Accepted Answer

(b) 64 minutes. Rate ∝ 1/√M. r(H₂) = 50/20 = 2.5 mL/min. r(O₂) = 2.5 × √(2/32) = 0.625 mL/min. Time for 40 mL = 40/0.625 = 64 min → (b).

Answer

(a) 12 minutes
