How does the presence of enzymes affect the equilibrium position of the breakdown of carbohydrate into glucose?
Enzymes cannot affect the equilibrium of a reaction, nor can they cause a thermodynamically unfavorable reaction to proceed. They are catalysts and can only alter the activation energy and therefore the rate of the reaction.
How does Ka affect equilibrium position?
Equilibrium shifts towards the higher Ka
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)
Which of the following factors does not affect thr equilibrium of a chemical reaction when it is changed?
The value of the equilibrium constant K is only influenced by temperature.
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.

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

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.
Which of the following factors does not affect thr equilibrium of a chemical reaction when it is changed?
The value of the equilibrium constant K is only influenced by temperature.
How does an enzyme affect equlibirium?
Enzymes do not affect the position of equilibrium. They speed up both the forward AND backward reactions.
What information do you need to determine how a change in pressure will affect the equilibrium of a reaction?
The total number of moles of gas on each side of 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?
Heat of reaction.
What conditions would pressure affect the reaction rate?
If the reaction occurs in the gas phase
How does the present of a catalyst affect the rate of reactions?
A catalyst is a substance which speeds up the rate of reaction. After the reaction it remain chemically unchanged. It does NOT affect the position of equilibrium. There can also be negative or "poisoned" catalysts as in Rosenmunds reaction.
