Do the presence of an enzyme catalyst will affect the time taken for a reaction to reach equilibrium?
An enzyme catalyst will lower the amount of energy required to preform a reaction.
This in turn, will make it much easier for the reaction to start.
So yes, it will let a reaction reach equilibrium quicker.
Other factors affecting the time of reaction are:
The concentration of the reactants, (the less volume and more pressure you have will increase the rate of reaction)
The PH level (especially important for Biology reactions, protein enzymes are built for specific PH levels and will not work correctly if they are in another PH level, buffers can be used to stabilize pH levels)

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.
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)
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 does the presence of a catalyst affect the enthalpy change of a reaction?
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
If a catalyst is added to a system at equilibrium and the temperature and pressure remain constant there will be no affect on the?
Equilibrium position. The catalyst speeds up the rate at which equilibrium is reached by lowering the activation energy for both the forward and reverse reactions equally. The concentrations of reactants and products at equilibrium remain the same.

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.
How would the equilibrium concentration of H2O be affected by adding a catalyst to the mixture?
Adding a catalyst to the mixture would not affect the equilibrium concentration of H2O. A catalyst speeds up the rate of the forward and reverse reactions equally, without changing the position of the equilibrium. This means that the equilibrium concentration of H2O would not be affected by the presence of a catalyst.

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)
What happens when ethanol and ethanoic acid react in the presence of acid catalyst?
When ethanol and ethanoic acid react in the presence of an acid catalyst, they undergo an esterification reaction to form ethyl ethanoate (ester) and water. This reaction is reversible and reaches equilibrium. The acid catalyst helps to increase the rate of the reaction but does not affect the overall stoichiometry.
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.

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. :)
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.
What effect does a catalyst have on a system equilibrium?
The correct answer is a simple one: The system is unaffected by a catalyst in a system in equilibrium.
How does the presence of a catalyst affect the enthalpy change of a reaction?
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
How does the presence of a hydrogen peroxide catalyst affect the rate of a chemical reaction?
The presence of a hydrogen peroxide catalyst can increase the rate of a chemical reaction by providing an alternative pathway with lower activation energy, allowing the reaction to occur more quickly.
If a catalyst is added to a system at equilibrium and the temperature and pressure remain constant there will be no affect on the?
Equilibrium position. The catalyst speeds up the rate at which equilibrium is reached by lowering the activation energy for both the forward and reverse reactions equally. The concentrations of reactants and products at equilibrium remain the same.
Do catalyst increase equilibrium constant?
No they do not. A catalyst is a thing (atom, molecule, element, etc.) that speeds up a chem. rxn by lowering the activation energy without being altered itself. So it only cause the reaction to occur faster, but will not have any affect on the equilibrium. Also, since the catalyst is not altered, it should 'come out' exactly as it 'went in.'
