6 sample questions

Question 1.
What does the Maxwell-Boltzmann distribution illustrate?
Show hintHide hint
Think about how temperature affects energy.
Question 2.
Define activation energy.
Show hintHide hint
It's related to the energy barrier that must be overcome.
3Question 3.
What does the Maxwell-Boltzmann distribution show?
- The chemical formula of gases
- The distribution of kinetic energies of molecules
- The speed of gas molecules at high pressure
Show hintHide hint
Remember how energy is related to molecular speed.
4Question 4.
True or False: Increasing temperature decreases the number of molecules with energy above the activation energy.
- True
- False
Show hintHide hint
Think about what happens when you heat something.
Question 5.
Explain how Maxwell–Boltzmann distribution influences reaction speeds in catalytic converters of vehicles.
Show hintHide hint
Consider temperature changes during car operation.
Question 6.
A gas reaction requires an activation energy of 50 kJ/mol. How does increasing temperature from 300 K to 330 K affect the fraction of molecules with enough energy to react?
Show hintHide hint
Utilize the exponential expression for fraction related to activation energy.
