Chemisches Gleichgewicht

A reversible chemical reaction represents a chemical process that proceeds in both forward (left to right) and reverse (right to left) directions. When …

Consider the oxidation of sulfur dioxide: For a reaction that begins with a mixture of reactants only, the product concentration is initially equal to …

Homogeneous Equilibria for Gaseous Reactions For gas-phase reactions, the equilibrium constant may be expressed in terms of either the molar …

The equilibrium constant for a reaction is calculated from the equilibrium concentrations (or pressures) of its reactants and products. If these …

The status of a reversible reaction is conveniently assessed by evaluating its reaction quotient (Q). For a reversible reaction described by m A + n B …

Being able to calculate equilibrium concentrations is essential to many areas of science and technology—for example, in the formulation and dosing …

A system at equilibrium is in a state of dynamic balance, with forward and reverse reactions taking place at equal rates. If an equilibrium system is …

For gas-phase equilibria, changes in the concentrations of reactants and products can occur with altered volume and pressure. The partial pressure, P, of …

Consistent with the law of mass action, an equilibrium stressed by a change in concentration will shift to re-establish equilibrium without any change in …

If a reaction has a small equilibrium constant, the equilibrium position favors the reactants. In such reactions, a negligible change in concentration may …
