A container has a mixture of two gases, hydrogen and oxygen at rom temperature. Which keeping the temperature. Which one of the followingg statements is true? (If `c_(H) and c_(O)` are the root mean square velocities of hydrogen and oxygen molecules respectively)

Options

A. `c_(H) gt c_(O)`
B. `c_(H) lt c_(O)`
C. `c_(O)=4c_(H)`
D. `c_(O)=16c_(H)`

Answer

A

Explanation

`(C_(H))/(C_(O))=sqrt((M_(O))/(M_(H)))=sqrt((32)/(2))=sqrt(16)`
`(C_(H))/(C_(O))=4" "thereforeC_(H) gt C_(O)`.
