The most probable speed is the peak. The average speed and RMS speed are located to the right of the peak because the long tail of fast-moving molecules shifts the average and RMS values higher. 3. Maxwell-Boltzmann POGIL Answer Key Breakdown
The shape and position of the curve remain the same because speed distribution depends on temperature and molar mass, not the total amount of gas. However, the area under the curve doubles because the total number of particles has doubled.

What is the Maxwell-Boltzmann distribution? (article) | Khan Academy The most probable speed is the peak
An advanced extension question modified from standard POGILs:
The Maxwell–Boltzmann distribution | AP Chemistry | Khan Academy
The average speed is given by:
The lighter gas (Helium) will display a wider, flatter curve shifted far to the right. The heavier gas (Neon) will display a tall, narrow peak shifted to the left. Scenario C: Integrating Activation Energy ( Eacap E sub a ) and Kinetics
Slightly to the right of the peak. $$v_avg = \sqrt\frac8RT\pi M$$ Use this to find the mean of the molecular speeds.
a) Which temperature has a larger fraction of molecules with energy greater than the activation energy (E_a)? Explain in terms of the shape of the curve. Maxwell-Boltzmann POGIL Answer Key Breakdown The shape and
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.
"Why does the distribution curve for a gas at a given temperature always start at the origin (0,0)?"
