A constant volume and temperature conditions, the rate of diffusion `D_(A)` and `D_(B)` of gases `A` and `B` having densities `rho_(A) and rho_(B)` are related by the expression

Options

A. `D_(A) = [D_(B) rho_(A)//rho_(B)]^(1//2)`
B. `D_(A) = [D_(B) rho_(B)//rho_(A)]^(1//2)`
C. `D_(A) = D_(B) [rho_(A)//rho_(B)]^(1//2)`
D. `D_(A) = D_(B) [rho_(B)//rho_(B)]^(1//2)`

Answer

D

Explanation

`(D_(A))/(D_(B)) = sqrt((rho_(B))/(rho_(A)))`
