Equilibrium Constants

Equilibrium constants are a measure of the concentration of products and reactants in a chemical reaction at balance, or equilibrium, where the rates of forward and reverse reactions are equal. A large equilibrium constant indicates that products are favored, while a small constant suggests that reactants dominate. This constant provides insight into how far a reaction proceeds before reaching a stable state, helping chemists understand and predict chemical behavior in various conditions, such as temperature and pressure. Essentially, it helps gauge the completeness of a reaction.
