Question

At 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.
(a) $D_A =\bigg [D_B \frac{\rho_A}{\rho_B}\bigg ]^{1/2}$
(b) $D_A = \bigg [D_B \frac{\rho_B}{\rho_A}\bigg ]^{1/2}$
(c) $D_A = D_B\bigg \lgroup \frac{\rho_A}{\rho_B}\bigg \rgroup ^{1/2}$
(d) $D_A = D_B\bigg \lgroup \frac{\rho_B}{\rho_A}\bigg \rgroup ^{1/2}$
