Vedclass · Answer

(C) Graham's law of diffusion states that the rate of diffusion $r$ of a gas is directly proportional to its partial pressure $P$ and inversely proportional to the square root of its molar mass $M$.Mathematically,$r \propto P / \sqrt{M}$.Therefore,for two gases $A$ and $B$,the ratio of their rates of diffusion is given by:$r_A/r_B = (P_A/P_B) 	imes \sqrt{M_B/M_A} = (P_A/P_B)(M_B/M_A)^{1/2}$.

According to Graham's law of diffusion at a given temperature,the ratio of the rate of diffusion $r_A/r_B$ for gases $A$ and $B$ is given by:
