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 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.
Can a catalyst change rate of reaction equilibrium position or both?
A catalyst cannot change the equilibrium position. However, it can change its rate.
How do you reach equilibrium fast?
Simply use a catalyst if you don't want to change the position of the equilibrium.
If a catalyst is added to a system at equilibrium and the temperature and pressure remain constant?
Heat of 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?
Heat of reaction.
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.
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.
Can a catalyst change rate of reaction equilibrium position or both?
A catalyst cannot change the equilibrium position. However, it can change its rate.
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 would the equilibrium concentration of H2O be affected by adding a catalyst to the mixture?
None. A catalyst affects only the rate of reaction, and if the reaction is already at equilibrium, the net rate of the reaction is zero and remains so after a catalyst is added.
How do you reach equilibrium fast?
Simply use a catalyst if you don't want to change the position of the equilibrium.
What happens to the amount of product when you use a catalyst in equilibrium?
The yield of reaction is improved.
If a catalyst is added to a system at equilibrium and the temperature and pressure remain constant?
Heat of reaction.
What happens to the value of kc when Catalyst is added to a chemical system at equilibrium?
It will remain Same Or Unchanged
If a catalyst is added to a system at equilibrium and the temperature and pressure remain constant there will be no affect on the?
Heat of reaction.
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.'
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. :)
