CHEMISTRY- 6.9 Mean Free Path, Diffusion, and
Effusion of Gases- STUDY GUIDE WITH 100%
CORRECT SOLUTIONS
Mean Free Path - ✔✔Average distance between molecular collisions.
Diffusion - ✔✔Gas molecules spreading due to concentration gradient.
Effusion - ✔✔Gas escaping through a small hole into vacuum.
Root Mean Square Velocity - ✔✔Average velocity of gas molecules at a
temperature.
Molar Mass - ✔✔Mass of one mole of a substance in g/mol.
Concentration Gradient - ✔✔Difference in concentration across a distance.
Graham's Law of Effusion - ✔✔Rate of effusion inversely proportional to molar
mass.
