Question

Which one of the following gas diffuses faster? Chlorine, Fluorine, Helium or Hydrogen

Answer 1

Answer:

Figure it out from their molar masses. Assuming constant temperature, they will have the same kinetic energy so the one with the lowest density (and lower molar masses) will diffuse the fastest.

Answer 2

Answer:

The rate of diffusion of hydrogen gas is the highest.

Explanation:

According to Graham's law of diffusion,

r ∝ 1/√M

This means that the rate of diffusion of a gas is inversely proportional to the square root of its molecular mass.

Thus, the one with the lowest molecular mass has the highest rate of diffusion.

The molecular mass of the following compounds is as follows.

He = 4 g

H₂ = 2 g

Cl₂ = 70.906 g

F₂ = 32 g

Hydrogen has the least molecular mass and thus the rate of diffusion of hydrogen gas is the highest.
