Sketch what happens to the M-B distribution curve if: a) You double the temperature of a gas. b) You replace the gas with one of double the molar mass at the same temperature.
). Compare their average kinetic energies and sketch their superimposed distributions.”
Always remember that the total area under any Maxwell-Boltzmann curve represents the whole sample. If you change a variable and make the curve wider, you must draw the peak lower.
A frequent extension prompt asks students to draw a vertical line representing Activation Energy ( Eacap E sub a Sketch what happens to the M-B distribution curve
“Using a Maxwell-Boltzmann distribution graph, explain why a modest
Heavier molecules (like Xenon) move slower and have a narrower, taller distribution.
If you are working on a specific calculation or a tricky graph in your worksheet, let me know: The specific or temperatures your prompt is comparing Whether your graph plots molecular speed or kinetic energy Compare their average kinetic energies and sketch their
) on a Maxwell-Boltzmann kinetic energy distribution curve. Use this model to explain why a tiny increase in temperature can cause a massive increase in the rate of a chemical reaction.”
) to maintain that energy. Lighter gases spread out more across the velocity axis. 3. Activation Energy and Reaction Rates Mark a line for "Activation Energy" ( cap E sub a
If you are working through a Maxwell-Boltzmann distribution POGIL worksheet, keep these quick reference rules in mind to verify your answers: If you are working on a specific calculation
b) has higher most probable speed.
If you have 2 moles of gas instead of 1 mole at the same temperature, the of the curve remains identical, but the area under the curve doubles. Maxwell-Boltzmann Distributions Explained - AP Chemistry S
