It doesn't. The whole point in a catalyst is that the only thing it does, is speeds up the reaction. It does not change or affect it in any other way.
However, factors which can change yield of reaction are temperature and pressure.
For example, take the manufacture of ammonia.
Pressure is measured in Atmospheres (atm)
Temperature is measured in degrees celcius (oC)
Companies that manufacture ammonia generally use 10 atms, and at least 450oC
Increasing the pressure above around 10 atms, reduces yield. Having temperature that high, also reduces yield, but as well as the catalyst, it increases the speed of the reaction.
What else can I help you with?
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.
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. :)
What can reduce the amount of energy needed for a chemical reaction to take place?
adding a catalyst to the reaction
In a chemical reaction does the amount of matter increase or decrease?
In a chemical reaction, the amount of matter remains the same. This is known as the Law of Conservation of Mass, which states that matter cannot be created or destroyed in a chemical reaction; it can only be rearranged.
What are the features of catalyst?
A catalyst alters (usually increases) the speed of a chemical reaction in which there is no net change in the amount of catalyst present after reaction is complete.

How do catalyst and inhibtors affect reaction rate?
A catalyst speeds up the reaction and lowers the amount of heat needed.

What are the salient features of catalyst?
A catalyst alters (usually increases) the speed of a chemical reaction in which there is no net change in the amount of catalyst present after reaction is complete.
How would a catalyst change the reaction energy diagram?
The overall enthalpy change in a common reaction would not change. Only the path to get there would change. A catalyst basically lessens the activation energy required to get the reaction to take place.

What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
What amount of catalyst remains at the end of a reaction?
At the end of a chemical reaction, ideally, the amount of catalyst remains unchanged. Catalysts facilitate the reaction by providing an alternative pathway with a lower activation energy but are not consumed or altered in the process. Therefore, the initial amount of catalyst should equal the final amount, assuming no side reactions or degradation occur.
How do catalyst affect the energy of reaction?
Catalysts greatly reduce the amount of activation energy needed to begin a reaction.
Is increase up or down?
Increase means to go up or get bigger in amount. Decrease means to go down or to get smaller in amount.
