maxwell boltzmann distribution Flashcards
1
Q
where is the mean energy indicated?
A
middle of graph
2
Q
where is the most probable energy of particles indicated?
A
peak of curve
3
Q
what does the total area under the graph show?
A
the total number of molecules
4
Q
what would the graph look like if temperature increased? why?
A
curve shifts right, lower peak
- due to more particles having activation energy
5
Q
what would the graph look like if the temperature decreased? why?
A
curve shifts left, higher peak
- due to less particles having activation energy
6
Q
what would the graph look like if a catalyst was added? why?
A
shape of curve doesn’t change BUT the position of the activation energy shifts left
- so that greater proportion of of molecules have sufficient energy to react
