At constant volume and temperature conditions, the rates of diffusion `r_(A)` and `r_(B)` of gases A and B having densities `P_(A)` and `P_(B)` are related by the expression :

A

`r_(A)=r_(B).(p_(A)//p_(B))^(2)`

B

`r_(A)=r_(B)(p_(A)//p_(B))^(1//2)`

C

`r_(A)=(r_(B).p_(A)//p_(B))^(1//2)`

D

`r_(A)=r_(B)(p_(A)//p_(B))^(1//2)`

Text Solution

Verified by Experts

The correct Answer is:
b
(b) According to Grahm's law
`rprop(1)/(sqrt(d)), " "(r_(1))/(r_(2))=sqrt((d_(2))/(d_(1)))` at constant P and T
