A flask contains argon and chlorine in the ratio of`2:1` by mass. The temperature of the mixture is `27^(@)C`. The ratio of average kinetic energies of two gases per molecule is

A

`1 : 1`

B

`2 : 1`

C

`3 : 1`

D

`6 : 1`

Text Solution

Verified by Experts

The correct Answer is:
B
`m_(alpha) : m_(cl) = 2 : 1`
`T = 27^(@)C`
`(K.E)_(avg) = (3)/(2) K.T`
Average kinetic energy is independent of nature of gas. It depends on temperature only.
