The rate of reaction often increases when catalysts are added. Catalysts can either lower the activation energy required for the reaction to happen, so that means more molecules will have enough energy to react than if the activation energy were higher. Catalysts can also be like substrates that act as a site for holding the molecules in the correct position to react. Always remember that molecules need to collide in the correct position with enough energy in order to react, and so catalysts will aid these two requirements and increase the reaction rate.
There are catalysts that slow the reaction, but it's not common.

What happens to the reaction rate when a catalyst is used in a chemical reaction?
When a catalyst is used in a chemical reaction, the reaction rate typically increases. This is because the catalyst provides an alternative reaction pathway with lower activation energy, allowing the reaction to proceed more quickly. Catalysts themselves are not consumed in the reaction and can be reused.
What does a catalyst do to the rate of a chemical reaction?
A catalyst is a substance that speeds up the rate of a chemical reaction without changing the substance. It does this by reducing the minimal reaction energy. A catalyst is not used up in a reaction therefore they last indefinitely.
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.
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.
What effect does catalyst on a reaction?
A catalyst speeds up the rate of a reaction.
What effect does a catalyst having a reaction?
A catalyst speeds up the rate of a reaction.

How is the term catalyst related to reaction rate?
The catalyst is a substance added to the reaction to speed it up. All in all, thecatalystlowers the reaction rate.

Why a catalyst is not involved chemically in chemical reaction?
The catalyst is not a reactant; a catalyst only favors a chemical reaction, the reaction rate and yield.

What is the catalytic efficiency formula used to calculate the effectiveness of a catalyst in a chemical reaction?
The catalytic efficiency formula is calculated by dividing the rate of the reaction with the catalyst by the rate of the reaction without the catalyst. This ratio helps determine how effective the catalyst is in speeding up the reaction.

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.
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.
When a catalyst is added to a reaction?
a catalyst increases the rate of the reaction by providing an alternative pathway with lower activation energy. The catalyst itself is not consumed in the reaction, allowing it to be reused multiple times. This results in faster reaction rates and potentially higher yields of products.
