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 a catalyst not do?
A catalyst does not change the equilibrium position of a reaction, meaning it does not alter the amount of products formed at equilibrium. Additionally, a catalyst does not affect the overall thermodynamics of a reaction, such as enthalpy or entropy. It also does not get consumed or chemically changed in the reaction it is catalyzing.
Which of the following factors does not affect thr equilibrium of a chemical reaction when it is changed?
The nature of the reactants and products does not affect the equilibrium of a chemical reaction when it is changed. The equilibrium constant is a characteristic of a particular reaction at a given temperature and does not depend on the identities of the substances involved.
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)
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.
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 effect does a promoter catalyst have on the position of the equilibrium?
A promoter catalyst can increase the rate of both the forward and reverse reactions in a reversible reaction without affecting the position of the equilibrium. It achieves this by lowering the activation energy, allowing the reaction to reach equilibrium more quickly but not altering the ratio of products to reactants at equilibrium.
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.

How does the concentration affect the rate and yield of ammonia?
Increasing the concentration of reactants typically increases the rate of ammonia production. However, it may not necessarily increase the yield of ammonia as the equilibrium position can be shifted depending on the reaction conditions. Increasing the concentration of reactants can favor the forward reaction, leading to higher yields of ammonia in some cases.
How does the presence of enzymes affect the equilibrium position of the breakdown of carbohydrate into glucose?
Enzymes can speed up the breakdown of carbohydrate into glucose without being consumed in the process. This acceleration of the reaction can shift the equilibrium towards more glucose formation by quickly converting the reactants into products, effectively lowering the activation energy required for the reaction to occur.
Why are the potassium and nitrate ions not involved in the equilibrium reaction?
Potassium and nitrate ions are spectator ions in the equilibrium reaction, meaning they do not participate in the chemical changes and are present on both sides of the equation without being consumed or produced. They do not affect the equilibrium or the equilibrium constant of the reaction.
What is the relationship between an enzyme and the equilibrium point of reaction it catalyzes?
Enzymes do not affect the equilibrium point of a reaction they catalyze. Instead, enzymes increase the rate of reaction by lowering the activation energy barrier. The equilibrium point of a reaction is determined by the free energy difference between products and reactants at equilibrium, which remains unchanged in the presence of an enzyme.
