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.
What is the effect of adding more water to the following equilibrium reaction?
Equilibrium is pushed to the reactant side
What does Le Chatelier's principle state?
A reaction at equilibrium will respond to balance a change - apex (Explanation): The answer is NOT "a new equilibrium ratio will form", because although this is true, it will not necessarily always happen and is not what le chatelier's principle is about. His principle focuses on the reaction changing to cancel out or balance the change in equilibrium. Therefore, this is the correct answer.
What happens when reactant is added to a system at equilibrium?
The equilibrium of the system will be upset.
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.
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?
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.
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 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.
What are 3 factors that affect equilibrium system?
Eqilibrium is not affected by any of the factors such as pressure,volume,catalyst,forward or backward reactions
How do you reach equilibrium fast?
Simply use a catalyst if you don't want to change the position of the equilibrium.
How does adding more reactants effect equilibrium?
Le Chatelier's principle says that, when a equilibrium is disturbed by adding or removing one or more of the contents, the system will attain a new equilibrium to minimize its effect. So when reactants are added to the system, some of they will react and give products in order to gain the new equilibrium.
What is the effect of adding more water to the following equilibrium reaction?
Equilibrium is pushed to the reactant side
What happens to the amount of product when you use a catalyst in equilibrium?
The yield of reaction is improved.
