Effusion is the escaping of gas molecules or atoms through a pinhole.
Concept #1: Effusion
Concept #2: Rate of Effusion
Example #1: Rank the following in order of increasing rate of effusion.
O2 PF5 CO2 Xe
Concept #3: Graham’s Law of Effusion
Example #2: Calculate the ratio of the effusion rates of helium to methane (CH4).
