Chemical Equilibrium
... Changing the volume of a reactant container changes the concentration of gaseous reactants and therefore their partial pressures Equilibrium position will therefore move The value of Kc or Kp does NOT change Changing pressure by adding more of an inert gas has no effect of the equilibrium position - ...

Catalysis
Catalysis is the increase in the rate of a chemical reaction due to the participation of an additional substance called a catalyst. With a catalyst, reactions occur faster and require less activation energy. Because catalysts are not consumed in the catalyzed reaction, they can continue to catalyze the reaction of further quantities of reactant. Often only tiny amounts are required.
