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.

What are the factors affecting equilibrium that causes shifting?
Factors that can cause a shift in equilibrium include changes in concentration of reactants or products, changes in temperature, changes in pressure (for gases), and the addition of a catalyst. When these factors are altered, the equilibrium position will shift in order to minimize the effect of the change and restore equilibrium.
What is mass action effect?
The law of mass action stipulate that the rate of a chemical reaction is directly proportional to the product of the activities (or concentrations) of the reactants.
When will Le Chatelier's principle come into effect?
Le Chatelier's principle comes into effect when a system at equilibrium is disturbed by changes in temperature, pressure, or concentration. The principle states that the system will adjust to counteract the imposed change and restore equilibrium.
Does the time period of oscillation depend on the displacement from the equilibrium position?
As long as angular amplitude is kept small, the period does not depend on the angular amplitude of the oscillation. It is simply dependent on the weight. It should be noted that to some extent period actually does depend on the angular amplitude and if it gets too large, the effect will become noticeable.
What does Le Chateliers principle say about upsetting a system at equilibruim?
Le Chatelier's principle states that when a system at equilibrium is disturbed by a change in temperature, pressure, or concentration of reactants or products, the system will shift to counteract the disturbance and restore equilibrium. This means the system will adjust its conditions in order to minimize the effect of the disturbance and return to 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.
Why doesn't a catalyst effect the position of equilibrium in a chemical reaction?
A catalyst speeds up both the forward and reverse reactions equally, allowing the system to reach equilibrium faster without changing the position of that equilibrium. It lowers the activation energy required for the reactions to occur but does not alter the relative energies of the reactants and products. Thus, while a catalyst increases the rate at which equilibrium is achieved, it does not affect the concentrations of reactants and products at equilibrium.
What are the factors affecting equilibrium that causes shifting?
Factors that can cause a shift in equilibrium include changes in concentration of reactants or products, changes in temperature, changes in pressure (for gases), and the addition of a catalyst. When these factors are altered, the equilibrium position will shift in order to minimize the effect of the change and restore 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)
What is effective action?
The mass action effect is the shift in the position of equilibrium through the addition or removal of a participant in the equilibrium.
What effect would a catalyst have on the reaction A2 plus 2B2AB?
A catalyst would increase the reaction rate of A2 plus 2B2AB without being consumed in the process. It provides an alternative reaction pathway with a lower activation energy, allowing the reactants to convert to products more efficiently. However, a catalyst does not alter the equilibrium position of the reaction or the final products formed.
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.
What can effect equilibrium shifts?
Changes in concentration, pressure, or temperature can all affect the equilibrium position of a reaction. Adding or removing reactants or products, changing the volume of the container, or altering the temperature can lead to shifts in equilibrium to favor the formation of products or reactants. Additionally, catalysts do not affect the position of equilibrium but can speed up the attainment of equilibrium.
What does Le Chtelier's principle state?
Le Chatelier's principle states that a system at equilibrium will respond to a disturbance by shifting its equilibrium position in a way that minimizes the effect of the disturbance. This means if you change the conditions of a reaction at equilibrium, the system will adjust to counteract that change and establish a new equilibrium.

What effect does catalyst on a reaction?
A catalyst speeds up the rate of a reaction.
What does Le Châtelier's principle state?
A reaction at equilibrium will respond to balance a change. :D
