Questions - Maxwell Boltzmann Distribution Pogil Answer Key Extension

Effusion rate depends on the average speed ((v_avg = \sqrt\frac8RT\pi M)). The small difference in mass leads to a small difference in average speed.

Even though the temperature increased by only 100K, the reaction rate is 150 times faster . The M-B extension question forces students to realize that kinetic energy distributions are mercilessly exponential. Effusion rate depends on the average speed ((v_avg

No, the shape does not change.

"The fraction of molecules with sufficient energy is exquisitely sensitive to temperature because (E_a / RT) appears in the exponent. A 100K increase reduces the exponent magnitude, yielding a 150-fold increase in reactive collisions." Part 5: Common Extension Question 4 – Isotopes and Effusion Question: Consider two isotopes: (^235\textUF_6) and (^238\textUF_6) at the same temperature. Draw their M-B distributions. Why is the difference in average speeds small, but the difference in effusion rates significant? Answer Key Reasoning This connects the M-B distribution to Graham's Law of Effusion. The M-B extension question forces students to realize
