A catalyst cannot change the equilibrium position. However, it can change its rate.

What does a catalyst not do?

Catalysts do not change the postition of the reaction's equilibrium. Adding a catalyst will increase the rate of reaction, but it will do this by providing another pathway for the reaction to occur acros, meaning a lower activation enthalpy is needed. :)


How do you reach equilibrium fast?

To reach equilibrium faster, you can increase the concentration of reactants, raise the temperature (if it's an endothermic reaction), decrease the volume (for gases), or use a catalyst to speed up the reaction rate. It's important to remember that altering these factors can only help reach equilibrium faster, not change the position of the equilibrium itself.


What parameter involved in a chemical reaction will change with the addition of a catalyst?

The rate of a chemical reaction will change in the presence of a catalyst, unless the reaction is already at equilibrium.


Assuming that the reaction is at equilibrium what effect does the addition of a catalyst have on the equilibruim?

a catalyst lowers the activation energy for both the forward and reverse reaction. however, it does not change the potential energy of the reactants or products. it also does not affect the heat of reaction (delta h)


How does the catalyst affect the Keq value of a reacti on?

A catalyst does not affect the value of the equilibrium constant (Keq) of a reaction. The presence of a catalyst increases the rate of both the forward and reverse reactions equally, allowing the system to reach equilibrium more quickly but does not change the final equilibrium composition.

What effect does a promoter catalyst have on the position of the equilibrium?

By definition a catalyst cannot affect equilibrium because although a catalyst can speed up a chemical reaction, it cannot change the thermodynamics of it, and equilibrium is determined solely by thermodynamics. A catalyst may help a system reach equilibrium more quickly, but it will not change it. One possible way a catalyst could affect equilibrium is by introducing a catalyst that affects a different reaction involving the substrate or products of the original reaction, but this would be cheating since the system would no longer be closed.

How do enzymes affect the equilibrium constant of a reaction?

Enzymes do not affect the equilibrium constant of a reaction. They only speed up the rate at which the reaction reaches equilibrium, but do not change the position of the equilibrium itself.

What will change when a catalyst is added to a chemical reaction?

When a catalyst is added to a chemical reaction, the rate of the reaction will increase without being consumed in the process. This means that the reaction will reach equilibrium faster and require less activation energy. The overall chemical equilibrium and products formed will remain the same.


Is it true that a change in pressure may affect the equilibrium position but has no effect on the equilibrium constant?

Yes, a change in pressure may affect the equilibrium position by shifting the reaction towards the side with more moles of gas to relieve the pressure change, but it has no effect on the equilibrium constant because the equilibrium constant is determined solely by the reaction's intrinsic properties.


Why do solids not affect equilibrium in a chemical reaction?

Solids do not affect equilibrium in a chemical reaction because their concentration remains constant and does not change during the reaction. This means that the presence of solids does not impact the equilibrium position or the rate of the reaction.


will a catalyst change the enthalpy of a reaction in a chemical reaction?

No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!


How do solids affect equilibrium in a chemical reaction?

Solids do not affect the equilibrium of a chemical reaction because their concentration remains constant and does not change during the reaction. Only the concentrations of gases and dissolved substances in a reaction mixture can affect the equilibrium position.
