Chemguide: Support for CIE A level Chemistry

Learning outcome 7.1


Chemical equilibria: reversible reactions, dynamic equilibrium

Statements 7.1.2 and 7.1.3

These statements are about Le Chatelier's Principle and its use in working out what happens when you change the conditions on a reaction in dynamic equilibrium.

Before you go on, you should find and read the statement in your copy of the syllabus.

You will find this explained on the page about Le Chatelier's Principle.

You will find that the definition of Le Chatelier's Principle on that page is slightly differently phrased from the one in the syllabus. Learn the one in the syllabus.

You will find two links to "more detailed explanations". You can ignore these, although we will have a look at the relevant page after we have dealt with equilibrium constants later in this section.
