This page offers just enough to cover the requirements of one of the UK A level Exam Boards to show that reactions with large negative values of ?G° have large values for their equilibrium constants, A fairly gentle introduction to entropy and free energy suitable for current A level syllabuses. An introduction to the ideas surrounding chemical equilibria including the concept of a dynamic equilibrium, Le Chatelier's Principle, and a detailed look at the equilibrium aspects of the Haber Process, the Contact Process and the Looking at this from an equilibrium point of view. Suppose you have a piece of magnesium in a beaker of water. There will be some tendency for the magnesium atoms to shed electrons and go into solution as magnesium ions. The electrons will be left behind on the magnesium. In a very short time, there will be a build-up Explains what is meant by the stability constant of a complex ion, nd how it is affected by the entropy change during a ligand exchange reaction. If you aren't happy about how to write expressions for equilibrium constants, it is essential to follow this link before you go any further. Use the BACK button on your browser to AN INTRODUCTION TO GIBBS FREE ENERGY. This page introduces Gibbs free energy (often just called free energy), and shows how it can be used to predict the feasibility of reactions. If you have already read the page about how to do this with total entropy changes, you will find a little bit of repetition on this page. AN INTRODUCTION TO CHEMICAL EQUILIBRIA. This page looks at the basic ideas underpinning the idea of a chemical equilibrium. It talks about reversible reactions and how they behave if the system is closed. This leads to the idea of a dynamic equilibrium, and what the common term "position of equilibrium" means. How to use total entropy change to predict the feasibility of a reaction. An introduction to Gibbs free energy . . . Introducing Gibbs free energy, and how you can use it to predict the feasibility of reactions. The relationship between Gibbs free energy and equilibrium constants. . . A very brief introduction to the equation relating EQUILIBRIUM CONSTANTS: Kp. This page explains equilibrium constants expressed in terms of partial pressures of gases, Kp. It covers an explanation of the terms mole fraction and partial pressure, and looks at Kp for both homogeneous and heterogeneous reactions involving gases. The page assumes that you are Learning outcomes 5.4(a) and 5.4(b). These statements introduce the idea of Gibbs free energy change, and show how it can be calculated. Before you go on, you should find and read the statements in your copy of the syllabus. You won't be able to u$
