Catalysis

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Recognise that a catalyst increases the rate of formation of new substances by increasing the rate of a chemical reaction.           
• Recognise that increasing the surface area of a solid catalyst increases rate of reaction between substances in the gas state.  
• Recognise that a catalyst cannot increase the yield (total amount of product) of a chemical reaction.   
• Explain how increasing temperature increases the rate of reaction by increasing the frequency of successful collisions.           
• Identify an energy profile diagram that shows a catalysed reaction (with lowered activation energy).

The resources include details of common misconceptions and a summary of the research upon which the resources are based.
