Key knowledge:
• chemical reactions with reference to collision theory, including qualitative interpretation of Maxwell-Boltzmann distribution curves
• the comparison of exothermic and endothermic reactions including their enthalpy changes and representations in energy profile diagrams
• factors affecting the rate of a chemical reaction including temperature, surface area concentration of solutions, gas pressures and presence of a catalyst
• the role of catalysts in changing the rate of chemical reactions with reference to alternative reaction pathways and their representation in energy profile diagrams.
