Standard Equilibrium Constants of Reactions Part

We write the general equation for a chemical reaction in the form  

The standard equilibrium constant of reaction (4) is defined by the relation  

Like the jLif s, therefore depends only on temperature T. It follows immediately that 

A A = A ffinal state of system) - A (initial state of system). (9) 

This notation is nevertheless widely used, and similarly Seve/ab is often denoted by the symbol AG and called the standard change of Gibbs function or standard (Gibbs) free energy change for the reaction. Equation (6) may then be rewritten in the more usual form
