Dynamic equilibrium

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

• Recognise that a reactant added in excess will still be present in the final reaction mixture.         
• Recognise that some chemical reactions are reversible.
• Recognise that, in a closed system, the forwards and reverse reactions can take place at the same time.   
• Explain, in terms of the equal rates of the forwards and reverse reactions, why no macroscopic changes are observed when a system is at dynamic equilibrium.   
• Recognise that if a reaction is at dynamic equilibrium the reaction mixture will contain both products and reactants.

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