Question

in 465cm of SO2 can diffuse through porous partition in 30 seconds.how long will 620cm of H2S take to diffuse though same partition...In this question why we use volume as a velocity explain it clearly...please answer in English ​

Answer 1

using Graham's law of diffusion

Rso2/RH2S = (MH2S/Mso2)^1/2

(465/30)/620/t = (38/64)^1/2

by solving

t= 30.82 sec
