Document Summary

Le chatelier"s principle: q and k have no units. Ratio of concentration to its reference standard state concentration. Activities or active concentrations: heterogenous equilibrium. Pure solid or liquid has the same concentration. Position of equilibrium is independent of the amount of solid or liquid as long as some is present. Pure solids and liquids do not appear in k: determining the direction of reaction: Q< k reactants decrease, and products increase, equilibrium shifts to the right. Q >k reactants increase, and products decrease, equilibrium shifts to the left. Q= k system is in equilibrium. If a change in imposed on a system at equilibrium, the position of equilibrium will shift in a direction that tends to reduce that change. Shift to the right more products: altering reaction conditions: Reactant added equilibrium shifts to the right. Product added equilibrium shifts to the left. Reactant removed equilibrium shifts to the left. Product removed equilibrium shifts to the right.
