Le Chatlier Principle

[Shirley Liu 2I]

If a reaction is already in equilibrium what will occur if a catalyst is added to the system? Will the reaction proceed forward or reverse or not at all?

[Shivangi_2J]

I think because a catalyst speeds up the forward and back reaction to the same extent, adding a catalyst does not affect the relative rates of the two reactions

[KimGiang2F]

Even though a system is at equilibrium, the reaction does not stop. Instead, it continues just as fast in the direction from reactants to products (the forward direction), as it does from products to reactants (the reverse direction). The addition of a catalyst speeds up the forward and back reaction to the same extent. Therefore, adding a catalyst does not affect the relative rates of the two reactions, it cannot affect the position of equilibrium.

[Luis_Yepez_1F]

Addin a catalyst wouldn't affect the equilibrium, rather it would just speed up the forward and reverse reaction.

A catalyst only affects the reaction rate. Products, reactants, equilibrium constants etc would not change.

[Chris Dis3L]

The catalyst does not interfere with the reaction at equilibrium. It merely speeds up the rate of the forward and reverse reactions.

[Casandra]

adding a catalyst has no effect on the equilibrium, it just speeds up reaction.

Adding a catalysts has no effect on the product or reactant, only speeds up the rate of reaction

[Ryan Yee 1J]

Adding a catalyst, in this case, would do nothing because the reaction is already at equilibrium. Catalysts only serve to increase the rate of reaction so if the reaction was not at equilibrium then it would just achieve equilibrium quicker than an uncatalyzed reaction.

[kausalya_1k]

Adding a catalyst will speed up both the forward and reverse reaction rates. However, as long as both the forward and reverse reaction rates are still equal to each other, then the reaction is still at equilibrium.

This website has a section called "The Effect of a Catalyst on Equilibrium" that might help you understand more thoroughly what happens if a catalyst is added: https://courses.lumenlearning.com/boundless-chemistry/chapter/factors-that-affect-chemical-equilibrium/
