CHEMICAL EQUILIBRIUM 14.1 THE CONCEPT OF EQUILIBRIUM AND THE EQUILIBRIUM CONSTANT Many chemical reactions do not go to completion but instead attain a state of chemical equilibrium. Chemical equilibrium: A state in which the rates of the forward and reverse reactions ...

Chapter 8, Acid-base equilibria
www.bu.eduThis equation is called the autoionization of water and its equilibrium constant is known as the water autoionization constant Kw. At 25°C it is equal to Kw =@H3O+D@OH-D=1.0μ10-14 Now, we have seen that the equilibrium constant of a sum of two reactions is the product of the equilibrium constants of the summed reactions.
