The ratio of kinetic energies of 2gm of ...

The ratio of kinetic energies of 2gm of `H_2 `and 4gm of `CH_4` at a given temperature is 

A

`4:1`

B

`2:32`

C

`1:4`

D

`16:2`

Text Solution

Verified by Experts

`2 gm H_2 = 1` mole, 4 gm `CH_4 = 1/4 ` mole.
`(KE_1)/(KE_2) = (n_1)/(n_2) = 1/(1//4) = 4`.
