Why doesn't Dalton's Law of Partial Pressures depend on the identity of the gases present?
It is assumed that all gas particles are behaving ideally and not interacting with one another. If that is true, the only difference between particles is associated with their mass. Since all of the gases are at the same temperature and have the same average kinetic energy, their masses don't have to be taken into account. The different gas particles exert the same force on the walls of the container, no matter what their mass.
Explain what the term "mean free path" describes. How does it change with decreasing pressure?
Mean free path describes the distance that a gas particle can travel before hitting another particle. As pressure decreases, the distance between particles increases, therefore increasing the mean free path of the particles.
