Which gas will diffusion faster within a system?

carbon dioxide
water vapor
ammonia (nh3)
methane(ch4)

Methane(CH₄).

Explanation:

∨ ∝ 1/√M.

where, ∨ is the rate of diffusion of the gas.

M is the molar mass of the gas.

∨₁/∨₂ = √(M₂/M₁)

Carbon dioxide: 44.01 g/mol.

Water vapor : 18.0 g/mol.

Ammonia (NH₃): 17.0 g/mol.

Methane(CH₄): 16.0 g.mol.

Since, methane has the lowest molar mass. So, it will diffuse faster within a system.
