Question

31). Which one of the following gas diffuses most rapidly?
a) Bromine
b) Carbon Dioxide
c) Methane
d) Nitrogen​

Answer 1

Answer:

methane

Explanation:

the gas with least molar mass diffuses fastest

Answer 2

Answer:

Methane

Explanation:

According to Grahms law of diffusion the rate of diffusion is inversely proportional to the square root of Molar mass

Molar mass of Br2:- approximately 160g mol¹-

Molar mass of NO2 :- 46 g mol¹-

Molar mass of CO2:- 44g mol¹-

Molar mass of CH4:- 16 g/mol

so the rate of diffusion is greatest for the compound with least molar mass. Hence methane will diffuse more rapidly than other three
