Date:Page:*How long will it take 600ml of H2 gas todiffuse through a porous portion, If 300ml of O2gas diffuse through it in 10 minutes under identical condition? |
|
Answer» Explanation: ANSWER According to Graham's law of diffusion, RATE of diffusion = t V
∝ M
1
[Here, M= molecular mass, V= volume and t= TIME] Thus, for H 2
gas, 200
=k 2
1
......(i) For O 2
gas, t 50
=k 32
1
........(II) where k is PROPORTIONALITY constant From equations (i) and (ii), we get 30×50 200×t
= 2
32
t= 200 16
×30×50
= 4 4×30
=30 min |
