Rate of diffusion is the change in number of diffusing molecules inside the cell over a time.
Since, net movement of diffusion depends on the concentration gradient, the rate of diffusion

\propto

concentration gradient across the membrane.
Also, the ratio of rate of diffusion is inversely proportional to the square root of the masses.

∵

Mass of

S O_{2} = 64

Mass of

C O_{2} = 44

Mass of

S O_{3} = 80

Mass of

PC l_{3} = 137

∴

Rate of diffusion of

S O_{2}, C O_{2}, PC l_{3}

and

S O_{3}

, is

C O_{2} > S O_{2} > S O_{3} > PC l_{3}

Q. The rates of diffusion of $S O_{2}, C O_{2}, PC l_{3}$ and $S O_{3}$ are in the following order

$C O_{2} > S O_{2} > PC l_{3} > S O_{3}$

$PC l_{3} > S O_{3} > S O_{2} > C O_{2}$

$S O_{2} > S O_{3} > PC l_{3} > C O_{2}$

$C O_{2} > SO > 2 > S O_{3} > PC l_{3}$

Q. The rates of diffusion of SO2​,CO2​,PCl3​ and SO3​ are in the following order

CO2​>SO2​>PCl3​>SO3​

PCl3​>SO3​>SO2​>CO2​

SO2​>SO3​>PCl3​>CO2​

CO2​>SO>2>SO3​>PCl3​

Q. The rates of diffusion of $S O_{2}, C O_{2}, PC l_{3}$ and $S O_{3}$ are in the following order

$C O_{2} > S O_{2} > PC l_{3} > S O_{3}$

$PC l_{3} > S O_{3} > S O_{2} > C O_{2}$

$S O_{2} > S O_{3} > PC l_{3} > C O_{2}$

$C O_{2} > SO > 2 > S O_{3} > PC l_{3}$
