Learn what heterogeneous equilibrium is, how to write equilibrium constant for heterogeneous reactions, and see examples of physical and chemical changes in different phases. Find FAQs and quiz on heterogeneous equilibrium.
An equilibrated system that contains products and reactants in a single phase is a homogeneous equilibrium; a system whose reactants, products, or both are in more than one phase is a heterogeneous equilibrium.
An example of heterogeneous equilibrium is as follows: Bromine occurs in a liquid state at room temperature. It easily changes into vapours and gives a red-brown colour in both states. At equilibrium, the rate of evaporation of bromine and the rate of condensation of bromine vapour are the same.
30 Ιαν 2023 · These types of changes are examples of heterogeneous equilibrium. For this type of equilibrium, the equilibrium constant is expressed by the partial pressure rather than by the ratio of pressure and concentration. For example, the dissolution of oxygen in water and the equilibrium constant are usually written in this way:
In thermodynamics, a heterogeneous equilibrium is an equilibrium state that involves a phase change of the system. In such an equilibrium, the system is not in thermal equilibrium with its surroundings; that is, the system is at a temperature different from that of the surroundings.
Heterogeneous Equilibria. A heterogeneous equilibrium involves reactants and products in two or more different phases, as illustrated by the following examples: $PbCl_2\; (s)$. ⇌. $Pb^ {2+}\; (aq) + 2Cl^−\; (aq)$. $K_c=\frac { [Pb^ {2+}]} { [Cl^−]^2}$. $CaO\mathit (s)+CO_2\; (g)$.
13 Μαρ 2024 · Examples of heterogeneous equilibrium include the breakdown of calcium carbonate into calcium oxide and carbon dioxide, whereas examples of homogeneous equilibrium include the reaction of carbon monoxide with hydrogen to produce methanol.
