Maxwell Boltzmann Distribution Pogil Answer Key Extension Questions Fix

For the same gas at two different temperatures, which temperature has a larger fraction of molecules moving faster than 1000 m/s? Why?

The Maxwell-Boltzmann distribution POGIL extension questions are not designed to be tricky for the sake of being difficult. They are crafted to dismantle naive mental models. The correct answers always circle back to three fundamental truths:

line. Because a larger proportion of particles now meet or exceed the required energy, the reaction rate increases.

The distribution curve does not change; instead, the activation energy ( cap E sub a ) line shifts to the left. Explanation:

The following answers address the typical extension questions found in POGIL activities: Flinn Scientific Particle Distribution at Absolute Zero (

At absolute zero, all molecular motion ceases according to the Kinetic Molecular Theory. Every particle would have zero speed, meaning there is no distribution or spread. Changing Molar Amounts (e.g., 2 moles vs. 1 mole):

Liquid water in an open beaker evaporates even at room temperature, far below its boiling point. Explain this using the Maxwell-Boltzmann distribution, and explain why the remaining liquid feels cooler.

). At a constant temperature, all gases have the same average kinetic energy.
