Re: Catalysts
No, catalysts do not shift a reaction, they simply speed it up. The equilibrium constant is unchanged, and the equilibrium concentration values are unchanged.

Re: Catalysts
Catalysts lower the activation energy of the reaction, so it will proceed more quickly, but a catalyst will not shift the equilibrium. The value of the equilibrium constant does not change with the introduction or removal of a catalyst.

Re: Catalysts
Catalysts don't shift equilibrium, but they do help the reaction establish equilibrium sooner by lowering activation energy (the energy required for an reaction to occur).

Re: Catalysts
catalysts can only affect the rate at which a reaction proceeds toward equilibrium, and as a result adding or removing it does not affects any values in the equilibrium equation. Only changes in temperature, concentrations of products or reactants, and pressure could cause a shift toward equilibrium.

Re: Catalysts
Furthermore, to add to the discussion, if you add a catalyst to a reaction that has reached equilibrium, the rates of the forward and reverse reactions will be increased by the same amount and the system will remain in equilibrium.

Re: Catalysts
According to Le Chatelier's principle, catalysts do not shift the reaction. Instead, adding it speeds up the reaction by lowering the activation energy. Hope this helps!

Re: Catalysts
Catalysts don't shift the reaction, because they speed up the forward and reverse reactions equally. If you think about it energetically, catalysts lower activation energy, which is lowered for both the forward and reverse reactions by the same amount.

Re: Catalysts
Hello,
Catalysts don't shift equilibrium because they don't change the concentration of reactants or products. They only increase the rate at which the consumption of reactants turns into products. I hope this helps.

Re: Catalysts
In an equilibrium, the reactions goes both ways, meaning that when a catalyst is introduced, the rate of reaction increases for reactions going both ways, hence it does not affect the equilibrium position.

Re: Catalysts
Catalysts don't affect equilibrium according to Le Chatliers, however when a catalyst is introduced it reduces the activation energy which increases the rates of both forward and reverse reactions the same amount.

Re: Catalysts
Catalysts only speed up a reaction. They do not cause a shift because there is no change in the concentration of products or reactants, only the rate at which reactants are converted to products changes. Hope this helps!
