Collision Theory

Question 1

What is needed for a reaction to occur?

Answer 1

Particles must collide.
Particles must have enough energy.

Question 2

Increasing concentration pressure means ..

Answer 2

There are more particles in the same volume (per unit volume).

Question 3

More particles in the same volume means…

Answer 3

The particles will collide more FREQUENTLY. Therefore there will be more FREQUENT collisions.

Question 4

What is activation energy?

Answer 4

The amount of energy particles need to react.

Question 5

The overall rate of reaction depends on:

Answer 5

Collision frequency.
Percentage success.

Question 6

What is collision frequency?

Answer 6

How often particles collide with each other.

Question 7

What is percentage success?

Answer 7

Wha percentage of collisions have enough energy.
