the rate of diffusion of He gas is 4 times that of CH4 gas . what is the ratio of length of gas diffused by 60sec in He gas and 45sec in CH4 gas. |
|
Answer» Answer: Rate of diffusion or EFFUSION of a gas at given CONDITIONS inversely proportional to the root of molecular mass & gas. r 1
/r 2
= M 2
/M 1
r CH 4
r He
= M He
M CH 4
= 4 16
=2 |
