Chemguide: Support for CIE A level Chemistry
Learning outcome 5.1(a)
This statement is little more than a simple introduction to chemical energetics, and almost certainly doesn't contain anything you don't already know. It deals with basic ideas about energy changes, and exothermic and endothermic reactions.
Before you go on, you should find and read the statement in your copy of the syllabus.
You will find everything you need to know on the introduction to chemical energetics page in the Physical Chemistry section of Chemguide.
