If the rate of diffusion of gas A is that of gas B, what will be the density ratio of A to B ()? — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

$r_A/r_B = \sqrt{d_B/d_A}$. Given $r_A/r_B = 5$, we have $5 = \sqrt{d_B/d_A} \implies 25 = d_B/d_A$. Therefore, the ratio $d_A/d_B = 1/25$.
