Chemie Heterogeneous Reaction Chemical reactions may be envisioned in terms of reactants and products and written in the general form A +bB - C +dD Reactants Products The equilibrium constant may be expressed in the form K - LORD up or K, - P2 where [C] represents the molar concentration of Catequilibrium. For a given reaction, the concentrations at equilibrium would have to be determined experimentally. In application, there are practical cases where some of the reactants and/or products do...
