Compléter Chemical Equilibrium: Forward and ReverseVersion en ligne Explore equilibrium concepts in a fill-in. par Anh Thu 1 The reaction is said to have reached equilibrium when the forward reaction rate is equal to the reaction rate . Notice that this is a dynamic condition , NOT a static one , although in appearance the reaction seems to have . 2 An example of an is a crystal of copper sulfate in a saturated solution of copper sulfate . Although to the observer the crystal seems to remain unchanged , there is actually an equal of crystal material with the copper sulfate in solution . As some solute comes out of solution , an equal is going into solution . 3 To express the rate of reaction in numerical terms , we can use the Law of Mass Action , which states : The rate of a chemical reaction is proportional to the product of the of the reacting substances . The concentrations are expressed in of gas per liter of volume or moles of solute per liter of solution . 4 Suppose , for example , that 1 mole / liter of gas A ? ( diatomic ) is allowed to react with 1 mole / liter of another diatomic gas , B ? , and they form gas AB ; let R be the rate for the reaction forming AB . The bracketed symbols [ A ? ] and [ B ? ] represent the concentrations in moles per liter for these diatomic molecules . Then A ? + B ? ? 2AB has the rate R = kf [ A ? ] x [ B ? ]
