1
Q

What is <i>Rate of Reaction</i>

A

<u>Change in concentration</u>

Time

2
Q

How does <i>Concentration</i> affect the rate of a chemical reaction.

A

There are more molecules per unit volume so are more likely to collide successfully.

3
Q

How does <i>Temperature</i> affect the rate of a chemical reaction.

A

Molecules have more kinetic energy so there are more frequent collisions and more effective collisions as they have sufficient energy.

4
Q

How does <i>Catalyst</i> affect the rate of a chemical reaction.

A

Lowers the activation energy so more molecules have sufficient energy to have an effective collision and react.

5
Q

How does <i>Surface area</i> affect the rate of a chemical reaction.

A

It has a larger surface for collisions so there are more effective collisions.
