A jar has a mixture of `H_(2)` and `O_(2)` gas in the ratio of 1: 5. The ratio of mean K.E. of `H_(2)` and `O_(2)` molecules is :

Options

A. `1:1`
B. `1:5`
C. `1:4`
D. `4:1`

Answer

A

Explanation

K.E. of gas molecules is given by
`1/2mv^(2)=3/2kT`
Since in mixture temperature is same.
`therefore` K.E. of both the gas molecules will also be same. Thus correct choice is (a).
