Answer:

The lighter a gas is, the faster it will tend to diffuse.

Using either the Molar mass below or the diffusion rates, you will see that CH4 is the lightest and with greatest diffusion rate hence the fastest.

THE ANSWER IS CH4

Explanation:

Use Grahams Law to determine diffusion rates

Diffusion rate =

[tex]= 1/\sqrt{molar mass}[/tex]

Molar mass:

CH4 = 16.04 g/mol

C2H2 = 26.04 g/mol

NO = 30.01 g/mol

O2 = 32 g/mol

Diffusion Rates using formula above:

CH4 = 0.24968

C2H2 = 0.19596

NO = 0.18254

O2 = 0.17677
