Answer:The nitrogen gas will diffuse fastest at a given temperature.
Explanation:
Graham duhem law: 'The rate of diffusion of gas is inversely proportional to the square root of the molar mass of the gas'.
[tex]r\propto \sqrt{\frac{1}{\text{Molar mass of the gas}}}[/tex]
So, the gas with lowest molar mass will diffuse fastest at given temperature:
Mass of chlorine gas = 70 g .mol
Mass of fluorine gas = 38 g/mol
Mass of Argon gas = 39.95 g/mol
Mass of nitrogen gas = 28 g/mol
[tex]N_2>F_2>Ar>Cl_2[/tex]
The nitrogen gas will diffuse fastest at a given temperature.
