If the ratio of the rates of diffusion of two gases A and B is 4 : 1. Then the ratio

If the ratio of the rates of diffusion of two gases A and B is 4 : 1. Then the ratio of their densities in the same order is

Options

(a) 16 : 1
(b) 4 : 1
(c) 1 : 4
(d) 1 : 16

Correct Answer:

1 : 16

Explanation:

Rate of diffusion ∝ 1 / √d. rA / rB = √dB / dA ⇒ 4 / 1 = √dB / dA ⇒ 16 / 1 = dB / dA ⇒ dA / dB = 1 / 16.

  • According to Graham's law of diffusion,
    RA/RB=√dB/dA
    or,(4/1)2=dB/dA
    or,16/1=dB/dA
    or,dA:dB= 1:16
