Maxwell Boltzmann Distribution Pogil Answer Key Extension Questions

This is a common trick question. The M-B distribution depends only on temperature and the mass of the particles. A catalyst works by providing an alternative reaction pathway with a lower activation energy (Ea) . It does not change the kinetic energy of the molecules. On a graph, you would redraw the vertical "Ea" line to the left (lower energy), but the bell curve itself remains identical.

in the sample; it must remain constant unless particles are added or removed. Extension Questions Analysis This is a common trick question

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. It does not change the kinetic energy of the molecules

: While different gases at the same temperature have different average speeds, they all share the same average kinetic energy Maxwell-Boltzmann Distribution - nanoHUB.org which determines the average speed

): This is the Boltzmann factor, which shows that as kinetic energy increases, the probability of finding a molecule with that energy drops off sharply. Key Concepts in Extension Questions 1. Comparing Vmpcap V sub m p end-sub Vavgcap V sub a v g end-sub Vrmscap V sub r m s end-sub

of the curve (the position of the peak and the width of the distribution) remains exactly the same because temperature, which determines the average speed, has not changed. However, the area under the curve

This is the critical insight for the Arrhenius equation. Increasing the temperature does two things:
