Question

calculate the rate of diffusion of methane gas when 16 ml of hydrogen gas diffuses in 2 seconds. then what is the rate of diffusion of CH2
​

Answer 1

Explanation:

r(CH4)/r (H2) = (MH2/MCH4) ^1/2

r (CH4) /16/2 = (MH2/MCH4) ^1/2

r (CH4) = 8×(2/16)^1/2

r (CH4) = 2.82 ml/sec

This is Graham law of diffusion
