Overall Expectations
By the end of the course, students will be expected to:
D1. Analyse technologies and chemical processes that are based on energy changes, and evaluate them in terms of their efficiency and their effects on the environment.
D2. Investigate and analyse energy changes and rates of reaction in physical and chemical processes and solve related problems.
D3. Demonstrate an understanding of energy changes and rates of reaction.

Big IdeasEnergy changes and rates of chemical reactions can be described quantitatively.
Efficiency of chemical reactions can be improved by applying optimal conditions. Technologies that transform energy can have societal and environmental costs and benefits. |
Guiding QuestionsHow do physical changes, chemical reactions and nuclear reactions differ in the amount of energy they release or absorb?
How can the energy of a system be determined? What factors affect the rate at which chemical reactions occur? |
