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.
How do you reach equilibrium fast?
Simply use a catalyst if you don't want to change the position of the 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 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. :)
will a catalyst change the enthalpy of a reaction in a chemical reaction?
No, a catalyst will not change reaction enthalpy. If it does so, then it is NOT a catalyst but a reactant in stead!
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.

What effect does the removal of heat have on the equilibrium position?
The temperature of a reaction will entirely change th equilibrium position for any given reaction. If I'm right, as you increase the temperature, the equilibrium shifts closer to the endothermic reaction as there is more heat to consume. It may also, of course, change other properties of the substances involved in the reaction, but that depends on the chemicals.
What is the LeChatlier?
The Chatelier's Principle states that when a dynamic equilibrium is disturbed by changing conditions then the position of equilibrium shifts to counteract the change to reestablish equilibrium. A chemical reaction is at equilibrium and experiences a change in pressure, temperature, or concentration of products , equilibrium will shift in opposite directions to offset change.
How does the presence of a catalyst affect the enthalpy change of a reaction?
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
Does the catalyst change the amount of energy released in the reaction?
no. the amount of catalyst does not influence the reaction; A catalyst simply provides an alternative route for the reaction with a lower activation energy.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
How does catalyst effect chemical change?
A catalyst alters the rate of a chemical reaction.
