Activation Energy

IQ3: What affects the rate of a chemical reaction?

Students:

● investigate the role of activation energy, collisions and molecular orientation in collision theory

● explain a change in reaction rate using collision theory

24. Rates of Reactions

This presentation introduces the concepts of activation energy and collision theory.

This worksheet provides a range of problems around collision theory.

Additional Resource

Desmos is an interactive graph generator, which may also be used to develop energy profile diagrams.

In the 5th lesson of Module 5 IQ1, we will revisit collision theory and relate it to equilibrium systems.
