Lesson Title: Today we are learning about
Why are catalysts often used in chemical reactions?

Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding

Success Criteria:	You will show your learning by...
Catalysts change the rate of chemical reactions but are not used up during the reaction. Different reactions need different catalysts. Enzymes act as catalysts in biological systems. Catalysts increase the rate of reaction by providing a different pathway for the reaction that has a lower activation energy. * An opportunity to investigate the catalytic effect of adding different metal salts to a reaction such as the decomposition of hydrogen peroxide. A reaction profile for a catalysed reaction can be drawn in the following form: (energy level diagram with reduced Ea with catalyst) Students should be able to identify catalysts in reactions from their effect on the rate of reaction and because they are not included in the chemical equation for the reaction. Students should be able to explain catalytic action in terms of activation energy. Students do not need to know the names of catalysts other than those specified in the subject content. Students should be able to recall how the presence of a catalyst affects the rate of chemical reactions.

Keywords:

Activation energy: The energy required to start a chemical reaction. (2)
Rate: The speed at which a chemical reaction proceeds. (1)
Enzyme: A protein manufactured by a cell, that acts as a biological catalyst. (1)
Catalyst: A substance that speeds up the rate of a chemical reaction, but is not consumed. Works by lowering the activation energy. (1)

AFL/Key Questions:

What are the key characteristics of a catalyst?
Catalysts change the rate of chemical reactions but are not used up during the reaction. Different reactions need different catalysts.
What is an example of a biological catalyst?
Enzymes act as catalysts in biological systems.
How do catalysts increase the rate of chemical reactions?
Catalysts increase the rate of reaction by providing a different pathway for the reaction that has a lower activation energy.
What would the reaction profile for a reaction in the presence of a catalyst look like compared to the same reaction without a catalyst?
The reaction profile for a catalyst would be lower than the pathway for the uncatalysed reaction. The catalyst reaction would be labelled Ea.
Are catalysts included in the equation for a chemical reaction? Give a reason for your answer.
Catalysts are not included in the chemical equation for a reaction. This is because they are not used up in the chemical reaction.
What is the relationship between catalytic action and activation energy?
The relationship between catalytic action and activation energy is that the more effective the catalyst, the lower the activation energy is.
What is the name of the catalyst used in the extraction of aluminium oxide?
The catalyst used in the extraction of aluminium oxide is cryolite.
How does the presence of a catalyst affect the rate of a chemical reaction?
The presence of a catalyst increases the rate of a chemical reaction.
