A gas mixture contains 1 mol each of two different gases, Would the average molecular kinetic energy of the two gases be equal?Would the rms speed be equal?

Explanation

In the mixture,both gases are the same temperature T. The average molecular kinetic energy is `3/2kT.` So, this is equal for both the gases.
But the rms speed is `sqrt((3RT)/M)`. As the molecular weight M is different for the two gases, the rms speed of the molecules is different.
