10.3 Boltzmann Distribution Flashcards
(4 cards)
1
Q
What is boltzmann distribution?
A
The spread of molecular energies in gases
2
Q
What are the key features of a boltzmann distribution graph?
A
-No molecules have 0 energy
-Area under the curve is equal to the total number of molecules
-No maximum energy for a molecule (curve does not meet the x axis_
3
Q
What happens to a boltzmann distribution graph at higher temperatures?
A
-The peak is lower and shifted to the right
-A greater proportion of molecules can overcome the activation energy
4
Q
What happens to a boltzmann distribution graph in the presence of a catalyst?
A
The activation energy is shifted to the left.
