Collision Theory Flashcards
1
Q
What is needed for a reaction to occur?
A
Particles must collide.
Particles must have enough energy.
2
Q
Increasing concentration pressure means ..
A
There are more particles in the same volume (per unit volume).
3
Q
More particles in the same volume means…
A
The particles will collide more FREQUENTLY. Therefore there will be more FREQUENT collisions.
4
Q
What is activation energy?
A
The amount of energy particles need to react.
5
Q
The overall rate of reaction depends on:
A
Collision frequency.
Percentage success.
6
Q
What is collision frequency?
A
How often particles collide with each other.
7
Q
What is percentage success?
A
Wha percentage of collisions have enough energy.
