If rate of diffusion of `A` is `5` times that of `B`, what will be the density ratio of `A` and `B` ?

Answer

a

Explanation

The rate of diffusion a gas is inversely proportional to the square root of its density
`sqrt((dB)/(dA)) = (r_(A))/(r_(B)) = 5` or `(dB)/(dA) = ((r_(A))^(2))/((r_(B))^(2)) = 25`
`(d_(A))/(d_(B)) = (d_(A))/(d_(B)) = 1/25`
