Nov 13, 2022 · When a chemical reaction is at equilibrium, any disturbance of the system, such as a change in temperature, or addition or removal of one of the reaction components, will "shift" the composition to a new equilibrium state. This is the only unambiguous way of verifying that a reaction is at equilibrium.
Jan 15, 2024 · Learn how to define and use the equilibrium constant (Keq) for a chemical reaction in solution. See examples, exercises, and key takeaways on how to construct and apply the Keq expression.
Learn about the state of a chemical reaction when the forward and backward rates are equal and the concentrations of reactants and products do not change. Find out the law of mass action, the equilibrium constant, Le Chatelier's principle, and the thermodynamic criteria for equilibrium.
Learn about the condition of chemical equilibrium, when the rates of forward and reverse reactions are equal, and the equation that describes it. Find out how the equilibrium constant and the standard Gibbs free energy are related.
Aug 14, 2020 · Equation 15.2.4 is called the equilibrium equation, and the right side of Equation 15.2.5 is called the equilibrium constant expression. The relationship shown in Equation 15.2.5 is true for any pair of opposing reactions regardless of the mechanism of the reaction or the number of steps in the mechanism.
Perhaps the most challenging type of equilibrium calculation can be one in which equilibrium concentrations are derived from initial concentrations and an equilibrium constant. For these calculations, a four-step approach is typically useful: Identify the direction in which the reaction will proceed to reach equilibrium. Develop an ICE table.
Learn how to write and manipulate equilibrium constant expressions for homogeneous and heterogeneous reactions. Find out how temperature, concentration, and reaction quotients affect equilibrium.
