4.7.4.6 Catalysts change the rate of chemical reactions but are not used up during the reaction. Different reactions need different catalysts. Knowledge of the names of catalysts other than those specified in the subject content is not required. Describe the characteristics of catalysts and their effect on rates of reaction. Identify catalysts in reactions. Explain catalytic action in of activation energy. 1 Define the term activation energy. Identify advantages of using catalysts in industrial reactions, eg reducing costs. Explain the effect of using a catalyst on the activation energy. WS 3.5 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. Research different catalysts and uses in industry. Research catalytic converters.
