Q

What is the Collision theory?

A

The collision theory states that the reacting particles must have enough energy when colliding to react and also be in the correct orientation.

Q

How does temperature affect the rate of a reaction?

A

They have more energy when colliding.
The frequency of collisions increases
This increases the rate of reaction

Q

How does concentration/pressure affect the rate of a reaction?

A

The frequency of collision increases
As the particles are more confined.

The energy of the collisions does not change

Q

How does surface area affect the rate of a reaction?

A

The higher the surface area, the more area the particles have to collide so the more frequent the collisions.

The energy is not affected.

Q

How does a catalyst affect the rate of a reaction?

A

A catalyst provides an alternative reaction pathway by lowering the activation energy.

Catalysts are specific to certain reactions.
