Energy and Processing: GCSE Chemistry

This course briefly looks at the topic of energy and processing as used in chemistry. Energy is observed in any reaction. How do we measure this energy? What processes are used in chemical manufacturing? Learn more here.

Course Introduction This course covers C3f: Energy and C3g: Batch or Continuous which is part of Module C3: Chemical Economics. This is examined on Paper 1 of GCSE OCR Chemistry B Course.

What is the difference between an exothermic and an endothermic reaction? How are they utilised? A common example would be the use of chemical hand warmers and chemical cold packs. Opposite reactions in similar packaging.

Calorimetry is a method used to measure the energy/heat that is released by substances when they are burned. This energy can be measured in joules or in calories. An experiment is described in this module.

Continuous processes are often used to manufacture chemicals that are needed constantly and in bulk. Ammonia via the Haber Process is an example. Batch processes are for smaller scale production. Pharmaceuticals for instance.

This short quiz will help in your review for the topic of energy and processing in chemistry. We recap on processes we have covered such as exothermic and endothermic reactions, the Haber Process and batch and continuous processing.
