Le Chatelier s principle equilibrium

Le Chatelier s principle demonstrates the effect of disturbances on chemical equilibrium. Le Chatelier s principle can also help predict whether or not disturbances will affect the equilibrium constant. None of these will affect the equilibrium constant EXCEPT the —... 

In (19-6), n has been made dimensionless. For a half-reaction, n is the number of electrons in the half-equation for the whole-cell reaction, n is the number of electrons in one of the multiplied half-equations before canceling the electrons. The Nernst equation is closely related to the laws of chemical equilibrium. Le Chatelier s principle applies to the potential of a cell in the same sense as it applies to the yield of an equilibrium process. Since Q is a fraction that has product concentrations in the numerator (top) and reactant concentrations in the denominator (bottom), an increased concentration of the product reduces the potential and an increased concentration of reactant raises the potential. 

If a chemical reaction is at equilibrium, Le Chatelier s principle predicts that adding a substance—either a reactant or a product—will shift the reaction so a new equilibrium is established by consuming some of the added substance. Removing a substance will cause the reaction to move in the direction that forms more of that substance. 

If energy in the form of heat is added to this system at equilibrium, Le Chatelier s principle predicts that the shift will be in the direction that consumes energy, in this case to the left. Note that this shift decreases the concentration of NH3 and increases the concentrations of N2 and H2, thus decreasing the value of K. The experimentally observed change in K with temperature t... 

There is a general rule called Le Chatelier s principle that can often be applied to systems at equilibrium. Le Chatelier s principle states that when a system at equilibrium is stressed, the system will shift in a direction that will reduce that stress. 

D is correct. The net equation is Ca(I03)2(s) + H+(aq) —> Ca2+(acf) + I03 (aq) + HI03(a ). CaOH2 in aqueous solution will produce both OH and Ca2+. The OH" will reduce the H+ in solution. Since the solution is saturated (in equilibrium), Le Chatelier s principle predicts that both of these changes will shift the reaction to the left producing Ca(I03)2(s).

When we alter the concentration of a reactant or product of a system at equilibrium, the rates of the forward and reverse reactions will no longer be equal. We say that a stress is placed on the equilibrium. Le Chatelier s principle states that when equilibrium is disturbed, the rates of the forward and reverse reactions change to reheve that stress and reestablish equilibrium.
