Question

The mixture of argon and chlorine gas is taken
in a flask with ratio of masses 2:1 and
temperature of mixture is 27 °C. Calculate the
following for both the gases:​

Answer 1

Answer:

ANSWER

The average translational kinetic energy (per molecule) of any (ideal) gas (be it monatomic like argon, diatomic like chlorine or polyatomic) is always equal to

2

3

k

B

T. It depends only on temperature and is independent of the nature of the gas.

Since argon and chlorine both have the same temperature in the flask, the ratio of average kinetic energy (per molecule) of the two gases is 1:1.
