An explanation I read from Chemistry - The Molecular Nature of Matter and Change Second Edition by Silberberg pg202-203 is that it is because that all the gases particles have the same average kinetic energy, therefore creates the same pressure. However, if one thinks carefully, there is something wrong with the statement. If the light and heavy particles have the same average kinetic energy, the heavy particles will travel much slower and hence create a lower pressure due to the infrequency of collision. I understand that this phenomena is proven expermentally but what is the theorical explanation. Does it have to do with the intermolecular forces and gravity exerted by the mass?
