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

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`
