CHEM 130 Lecture Notes - Lecture 36: Chemical Equilibrium, Partial Pressure, Equilibrium Constant
Document Summary
Chem 130: general chemistry: macroscopic investigations and reaction principles - Three ways to alter the equilibrium composition of a gaseous reaction mixture and possibly increase the yield product. Changing the concentrations by removing products or adding reactants to the reaction vessel. Changing the partial pressure of gaseous reactants and products by changing the volume. A catalyst cannot alter equilibrium composition, but it can change the rate at which a product is formed and affect the result. States that when a system in chemical equilibrium is disturbed by a change of temperature, pressure, or a concentration, the system shifts in equilibrium composition in a way that tends to counteract this change of variable. If a substance if removed or added to the equilibrium mixture in order to alter the concentration of the substance, a chemical reaction occurs to partially restore the initial concentration of the removed or added substance.
