Gaseous State

IIT JEE Questions › Physical Chemistry questions › Gaseous State

There are 2 containers having equal volume,temperature and total pressure. 1 contains 5 moles of N₂. the other one contains 3 moles of O₂ and 2 moles of He.For the same time-interval the gases are diffused outside. Find the ratio of rate of diffusion of N₂ to the rate of diffusion of the other gasous mixture (O₂+He).....

@Aditya, you have made the same mistake that i was going to make. are u sure that the rate of diffusion of O₂ and He from the 2nd container will be the same?

U know Molecular wt of O₂ is not equal to molecular weight of He..:)

i used M_effective = M₁n₁ + M₂n₂n₁+n₂

ya. by that method the ans wud cum .86 as u said. But see, thru an opening in the container u can't say that both He and O₂ will come out at the same rate.

HINT: U have to apply the concept of Partial pressure..
