Zeolites are crystalline structures of aluminum, silicon and oxygen with pores that can act as cages or channels for molecules. They are often used for separating molecules by their size. Answer the next four questions to determine if classical mechanics are sufficient to model a helium atom traveling through a zeolite. What is the de Broglie wavelength for a helium atom (m = 6.6 x 10-27 kg) traveling at v = 1000 m/s (typical speed for an He atom at room temperature). If the uncertainty in the position for the He atom is 10 À what is the minimum uncertainty of its velocity. Imagine the He atom is confined to motion along a line of length L = 10 Å. What is the closest quantum number for the confined atom traveling at 1000 m/s? (Use the 1-D particle-in-a-box model)
