Answer #1

Average kinetic energy of all gases are same at given temperature.

So, A is correct and D is wrong.

All molecules do not have same kinetic energy in a gas.

So, E is wrong.

RMS speed depends on. Molar mass of a gas beside temperature of the gas.

Since molar mass is different for SO2 and H2S, their rms speed would be different.

So, B is wrong

SO2 has higher molar mass than H2S.

So, SO2 would be slower as compared to H2S.

So, C is wrong.
