Chemistry - Year 12 :: Queen Elizabeth High School

AS Chemistry (OCR – H035)

There are two units at AS level (Chemistry for Life F331 (30%) and Chemistry of Natural Resources (50%)), each one across both teachers. Coursework (20%) is a moderated practical test taken in February. Both units are examined in May/June of Year 12.

Half Term 4 (March - April)
The chemical ideas in this module (The Atmosphere) are: giant covalent structures; rates of reaction; chemical equilibrium; radical reactions; the electromagnetic spectrum and the interaction of radiation with matter. A study of important chemical processes occurring in the atmosphere – the ozone layer and the greenhouse effect. the benefits and risks to us and the environment of CFCs and their replacements; how the evidence for the ozone ‘hole’ was overlooked; the conflicting evidence for the relation between increased concentration of greenhouse gases and global warming; the effect on the environment of CFCs and greenhouse gases; the ways in which society’s decision making has been informed by science in the matters of the ozone hole and global warming.	The chemical ideas in this module (The Atmosphere) are: radical reactions; A study of important chemical processes occurring in the atmosphere – the ozone layer and the greenhouse effect. use of reaction mechanisms as models to explain chemical reactions;
