Define the term "rate of reaction".

According to collision theory, what two conditions must be met for reactant particles to result in a chemical reaction?

List the four factors that can affect the rate of a chemical reaction.

Explain, using collision theory, why increasing the concentration of a reactant increases the reaction rate.

How would you increase the rate of a reaction between a solid lump of metal and an acid?

What is a catalyst?

How does a catalyst increase the rate of a reaction?

Explain why food is stored in a refrigerator to prevent it from spoiling.

How does the gradient (steepness) of a reaction-progress graph relate to the rate of reaction?

Why does the rate of most reactions decrease over time?

What is the name given to the minimum energy required for a collision to be successful?

Give an example of a biological catalyst.

If you increase the pressure of reacting gases, what happens to the rate of reaction?

A powdered solid reacts faster than a large lump of the same solid. What factor is responsible for this?

Describe a simple experiment to measure the rate of the reaction between calcium carbonate and hydrochloric acid.
