Document Summary
Diffusion and effusion diffusion - process by which one gas mixes with another effusion - process by which a gas escapes forma container through a small opening. Refer to notebook: diffusion and effusion rate, r, r a v, m a m. Graham"s law r1/r2 = sqroot (m2/m1) where m is molar mass. An element that exists as a diatomic gas at stp effused at 0. 324 times the rate of effusion of he under the same conditions. Molecules are constant colliding with each other, e. g he at 25c and 1 atm undergoes ~ Mean free path, for he at 25c and 1 atm is ~2x10^-7 m. symbol is lamda. Refer to notebook, diffusion laws contribute to the enrichment of uranium. Calculate the average volume of space / molecule in an ideal gas at 27c and 1 atm. Refer to notebook any set of conditions that leads to a high density for a gas, many molecules in a small space.
