15.2: The Equilibrium Constant Expression - …

25/08/2020· H2 ( g) + D2 ( g) ⇌ 2HD ( g) The equilibrium constant expression for this reaction is. K = [HD]2 [H2][D2] with K varying between 1.9 and 4 over a wide temperature range (100–1000 K). Thus an equilibrium mixture of H2, D2, and HD contains significant concentrations of both product and reactants.

Chapter 12 - Chemical Equilibrium - CHE 105/110

18/11/2020· So far in this text, when we present a chemical reaction, we have implicitly assumed that the reaction goes to completion. Indeed, our stoichiometric calculations were based on this; when we asked how much of a product is produced when so much of a reactant reacts, we are assuming that all of a reactant reacts. However, this is usually not the case; many reactions do not go to completion, and
