Two flasks A and B have equal volume. A ...

Two flasks `A` and `B` have equal volume. `A` is maintained at `300 K` and `B` at `600 K`. While `A` contains `H_(2)` gas, `B` has an equal mass of `CH_(4)` gas. Assuming ideal behaviours for both the gases, answer the following:
Flask in which pressure is higher

A

`A`

B

`B`

C

Both `A` and `B`

D

None

Text Solution

Verified by Experts

Since `P_(A)V=n_(A)RT_(A)` and `P_(B)V=n_(B)RT_(B)`
`:. (P_(A))/(P_(B))=(n_(A)T_(A))/(n_(B)T_(B))=8xx(300)/(600)=4`
`:. P_(A)gtP_(B)` or `P_(A)=4P_(B)`
