Two flasks `A` and `B` of equal volume are at temperature `100 K` and `200 K` containing `H_(2)` and `CH_(4)`, respectively. Which of the following is true about `KE` per mole (`KE=` Kinetic energy).

Options

A. `KE` per mole of `H_(2)` is twice that of `CH_(4)`
B. `KE` per mole of `CH_(4)` is twice that of `H_(2)`
C. `KE` per mole of `H_(2)` is equal to that of `CH_(4)`
D. `KE` per mole of `CH_(4)` is thrice that of `H_(2)`

Explanation

`overlinemu_(A)=sqrt((8RT_(A))/(pi M_(A)))`
`overlinemu_(B)=sqrt((8RT_(B))/(pi M_(B)))`
`(overlinemu_(A))/(overlinemu_(B))=sqrt((300)/(2)xx(16)/(600))=2`
`overlinemu_(A)=2overlinemu_(B)`
