Question

Which pair of the gases diffuses with the same rate at same temperature and pressure? (A)  CO and NO  (B)  NO2 and CO2  (C)  NH3 and PH3  (D)  NO and C2H6

Those gases which have same molecular weight, diffuses with the same rate at the same temperature and pressure, therefore NO and C2H6 gases diffuse with the same rate because their molecular weights are same i.e., 30.

Q. Which pair of the gases diffuses with the same rate at same temperature and pressure?

$CO$ and $NO$

$N O_{2}$ and $C O_{2}$

$N H_{3}$ and $P H_{3}$

$NO$ and $C_{2} H_{6}$
