Key Concepts

Chemical Equilibrium

Chemical equilibrium refers to the state in a reversible chemical reaction where the rates of the forward and reverse reactions become equal. At this point, the concentrations of reactants and products remain constant over time, not because the reactions have stopped, but because their changes balance each other out.

Equilibrium Constant

The equilibrium constant is a numerical value that characterizes a chemical reaction at equilibrium. It is defined as the ratio of the concentrations of products to reactants, each raised to the power of their respective stoichiometric coefficients. Importantly, this constant is dependent only on the temperature and is independent of the initial concentrations of reactants and products.

Impact of Initial Concentrations

While the equilibrium constant itself does not change with different starting concentrations, the initial amounts of reactants and products influence the path the reaction takes to reach equilibrium. Different initial conditions will generally lead to different equilibrium concentrations; however, once equilibrium is achieved, the ratio of these concentrations will adhere to the constant value defined by the equilibrium constant.
