What does a catalyst reduce to a chemical reaction?

Adding a catalyst a chemical reaction can occur with a lower activation energy.


What is the activation energy needed for a chemical reaction decreased by?

The activation energy is decreased by a catalyst.


What is Catalyst for chemical reaction?

A catalyst can improve the reaction rate or allows the realization of a chemical reaction with an energy lower than the activation energy.


What is the source of activation energy during chemical reaction?

A catalyst.


How does the catalyst affects the activation energy of a chemical reaction?

catalyst will generally reduce the activation energy


What activation energy is needed for a chemical reaction is decreased by?

The activation energy is decreased by a catalyst.


What effect does a catalyst have?

A catalyst speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does so by providing an alternative reaction pathway that requires less energy to initiate the reaction. The catalyst itself remains unchanged at the end of the reaction and can be used over and over again.


When a catalyst is present is more or less activation energy needed to start a chemical reaction?

When a catalyst is present, less activation energy is needed to start a chemical reaction. This is because the catalyst provides an alternative pathway for the reaction to occur, allowing it to proceed more readily. The catalyst achieves this by lowering the activation energy barrier for the reaction.


What will change when a catalyst is added to a chemical reaction?

When a catalyst is added to a chemical reaction, the rate of the reaction will increase without being consumed in the process. This means that the reaction will reach equilibrium faster and require less activation energy. The overall chemical equilibrium and products formed will remain the same.


How does catalyst affect the activation energy of chemical reaction?

The presence of a catalyst affects the activation energy of a reaction by lowering the activation energy, helping the reaction go faster and making it so the reaction does not have to use as much energy to fulfill the products.


What does a catalyst do in a chemical reaction?

Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.


What best explains the role of a catalyst in a chemical reaction?

A catalyst is a substance that speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does this by providing an alternative reaction pathway with a lower energy barrier. The catalyst itself is not consumed in the reaction and can be reused multiple times.
