IGCSE Chemistry Topic Questions Paper 2 Multiple Choice on Chemical Energetics
Concepts that the exams aim to test you on are:
6.1 Energetics of a reaction
Core
- Describe the meaning of exothermic and endothermic reactions
- Interpret energy level diagrams showing exothermic and endothermic reactions
Supplement
- Describe bond breaking as an endothermic process and bond forming as an exothermic process
- Draw and label energy level diagrams for exothermic and endothermic reactions using data provided
- Calculate the energy of a reaction using bond energies
6.2 Energy transfer
Core '
- Describe the release of heat energy by burning fuels
- State the use of hydrogen as a fuel
- Describe radioactive isotopes, such as 235U, as a source of energy
Supplement
- Describe the use of hydrogen as a fuel reacting with oxygen to generate electricity in a fuel cell. (Details of the construction and operation of a fuel cell are not required.)
