Hydrogen diffused through a porous plug
...Hydrogen diffused through a porous plug
thrice as fast as oxygen
at the same speed as oxygen
four times as fast as oxygen
twice as fast as oxygen
Correct answer is C
Using Graham's Law of Diffusion,
R1R2=√m2m1
RHRO=√mOmH
RHRO=√322
RHRO=√16=4
∴RH=4×RO
Therefore, hydrogen diffuses 4 times faster than oxygen.
