Answer:
The increasing order relative rate of diffusion from fastest to slowest will be: N>Ne>Ar>Kr
Explanation:
Graham's diffusion law states that the rate of diffusion of gas is inversely proportional to the square root of the molecular mass of the gas. Mathematically given as:
[tex]\text{Rate of diffusion}\propto \frac{1}{\sqrt{\text{Molecular mass of the gas}}}[/tex]
Higher the molecular mass slower will be the diffusion rate.In the given gases the molecular mass of Krypton, nitrogen ,argon and neon is 83.80 g/mol,14.01 g/mol,39.95 g/mol and 20.18 g/mol respectively.
Increasing order of molecular mass: Kr >Ar>Ne> N
So, increasing order relative rate of diffusion from fastest to slowest will be: N>Ne>Ar>Kr
