1 For a reaction to be practical, the equilibrium must favor products and the reaction rate must be fast enough to form them in a reasonable time. These two conditions depend on thermodynamics and kinetics respectively. Thermodynamics describes how the energies of reactants and products compare, and what the relative amounts of reactants and products are at equilibrium. Kinetics describes reaction rates (how fast a reaction occurs). Kinetics and Thermodynamics

4 Relationship Between Equilibrium Constant and Free Energy
Background image of page 4
5 Compounds that are lower in energy have increased stability. The equilibrium favors the products when they are more stable (lower in energy) than the starting materials of a reaction. Because G ° depends on the logarithm of K eq , a small change in energy corresponds to a large difference in the relative amount of starting material and product at equilibrium.
