Maxwell Boltzmann Distribution Pogil Answer Key Extension Questions Jun 2026
): The peak of the curve, representing the speed of the largest number of particles.
): Slightly to the right of the peak due to the curve’s "long tail." The speed associated with the average kinetic energy ( Pro-Tip: If the question asks why Vrmscap V sub r m s end-sub is higher than Vmpcap V sub m p end-sub
line expands dramatically. Therefore, a small temperature shift causes a disproportionately large increase in the fraction of molecules with enough energy to overcome the activation barrier, drastically speeding up the reaction. 4. The Effect of a Catalyst ): The peak of the curve, representing the
A common student error in extension questions is confusing the Most Probable Speed (the peak) with the Average Speed . Remind students that because the graph is "skewed" (not a perfect bell curve), the peak ($v_p$) will always be lower than the average ($v_avg$). This feature helps them correct that misconception.
In any POGIL distribution graph, the total area under the curve must equal 1 (representing 100% of the molecules). This feature helps them correct that misconception
equation, molar mass must be converted from grams per mole ( g/molg/mol ) to kilograms per mole ( kg/molkg/mol ). This is because Joules (inside the gas constant ) are defined using kilograms (
vmp
f(v) = 4π [m / (2πkT)]^(3/2) v^2 e^(-mv² / 2kT)
. This increase in the area under the curve to the right of the line illustrates that a much larger fraction of particles now possesses the minimum energy required to undergo a successful collision. Extension Question 4: Temperature vs. Variability ): The peak of the curve
These are slightly to the right of the peak, representing higher energy states. 2. POGIL Extension Question: The Effect of Temperature
