Question

Which of the following gases will have the same rate of diffusion under identical conditions?
(C = 12 g; H = 1g: 0 = 16 g N = 149)
(1)
(ii) 00,
(iii) NO
(iv) N
iv) CH4
(vi) CHg
(A) CO.CO,, C,H,
(B) CO2, CH4, N20
(C) C.Hg, N,O, CO2
(D) CO, N,, C, H4, C,H,​

Answer 1

Answer:

B

CO2andN2O

C

COandC2H4

both have the molecular weight 44both have the molecular weight 44

CO and C2H4 both have the molecular weight 44

Rate of difffusion is directly proportional to molecular weight

So both have the molecular weight 44 CO and C2H4 ave same rate of diffusion under similar conditions

Hence options B & C are correct.

Answer 2

Answer

B & C is a correct option
