Summary

Each topic is designed for teaching over roughly 1-2 lessons.

This unit considers two highly important topics in the area of physical chemistry – rates of reaction and chemical equilibria. This unit builds on an understanding that some chemical reactions are fast and some are considerably slower. Experimental work is presented as an essential method for monitoring the rate of a chemical reaction, with time devoted to the planning of such experiments, and the analysis and interpretation of the results. From factors that affect the rate of reaction including the role of activation energy when explaining the effect temperature on rate, to the world of catalysts, this unit illustrates the topic with thoughtful and carefully selected examples. The second phase of the unit concentrates on reversible reactions, and how these may attain a state of chemical equilibrium. The link between these two aspects is carefully explored and discussed. The final part of the unit concentrates on how to change the position of equilibrium by altering external conditions – a fascinating and challenging way to conclude this particular topic.

The complete series covers the AQA GCSE (9-1) Chemistry 8462 and combined science (Trilogy) 8464 specifications for Chemistry. Content relating to the separate Chemistry specification or Higher level material is indicated throughout for easy identification.
