Catalysis Pack – Heterogeneous, Homogeneous & Autocatalysis

A complete, ready-to-teach resource pack covering all key aspects of AQA A-level catalysis, designed to build deep conceptual understanding while maintaining a strong focus on exam success

What’s included

• Fully resourced lessons:
• Heterogeneous catalysis (surface processes)
• Homogeneous catalysis (intermediate formation)
• Autocatalysis (product as catalyst)
• Structured lesson slides using a clear First, Next, Then (FNT) approach
• Chemsheets-style worksheets for independent and guided practice
• Mini-whiteboard (MWB) retrieval questions embedded throughout
• Hinge questions to diagnose misconceptions in real time
• AQA-style exam questions with model answers, mark schemes, and examiner commentary
• Misconceptions and corrections explicitly addressed

Key content covered

• Definition and comparison of heterogeneous vs homogeneous catalysis
• Adsorption, active sites, and surface reactions
• Formation of intermediate species in homogeneous catalysis
• Role of transition metals and variable oxidation states (e.g. Fe²⁺/Fe³⁺)
• Energy profile diagrams and multi-step pathways
• Explanation of why catalysts lower activation energy
• Autocatalysis, including the manganate(VII)/ethanedioate reaction
• Interpretation of rate changes over time
• Links between kinetics, redox, and reaction mechanisms
