When asked to rank these speeds from lowest to highest based on the graph, the universal order is always:
Probability Density ^ _ | / \ <--- Most Probable Speed (Vmp) | / \ | / \ <--- Average Speed (Vavg) | / \ <--- Root-Mean-Square Speed (Vrms) |/___________\____________________> Molecular Speed (v)
POGIL activities usually start with basic data analysis (e.g., "identify the peak") but move into extension questions that require applying the theory to new scenarios. Here are common extensions and their answers.
). Use the Maxwell-Boltzmann distribution to justify why lighter gases escape into space while heavier ones are retained.”

). Molar mass affects velocity distributions, but it does not affect kinetic energy distributions at a set temperature.
The Maxwell-Boltzmann (M-B) distribution is the cornerstone of kinetic molecular theory. It explains why reactions happen at different rates when we change the temperature, why catalysts work, and even how our atmosphere escapes into space. In a typical POGIL activity, after mastering the basic shape of the curve (x-axis: speed/energy, y-axis: number of molecules), students encounter . These are designed to push beyond simple recall into synthesis and critical thinking.
This connects the M-B distribution to Graham's Law of Effusion.
