Catalysts are special substances that help speed up chemical reactions. They do this without being used up themselves. This is really important when we talk about reactions that can go both ways. Here’s how they work:
Speeding Up Reactions: Catalysts make it easier for reactants (the starting materials) to turn into products (the result of the reaction). They do this by lowering the energy needed for the reaction to happen. For example, using a catalyst can make a reaction happen 10 to 1,000,000 times faster!
Equilibrium Position: Catalysts don't change the final balance of the reaction. They make both the forward reaction (where reactants turn into products) and the reverse reaction (where products turn back into reactants) go faster. This means that the balance point is reached quicker, but the amounts of reactants and products stay the same.
Dynamic Equilibrium: In a dynamic equilibrium, the rate at which reactants become products is the same as the rate at which products turn back into reactants. Catalysts help this balance happen faster, but they don't change the ratio of the amounts of each substance. This ratio is described by something called the equilibrium constant, or ( K_{eq} ).
In short, catalysts make reactions happen faster and help reach balance sooner, but they do not change the final amounts of reactants and products in the reaction.
