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.
What role do catalysts play in chemical reactions?
A catalyst is a chemical species that alters the rate of a chemical reaction without undergoing any type of change. Such catalysts that slow down a reaction are called negative catalysts or poison.
What substances change the speed of your reactions?
Catalysts accelerate chemical reaction. Enzymes are examples of catalysts that speed up reactions in the body.
Why are catalysts important in chemical reaction?
Catalysts are important in chemical reactions because they change the rate of a chemical reaction. However, catalysts themselves are not actually a reactant of a reaction. For example, magnesium oxide is a catalyst to hydrogen peroxide, which speeds up the rate that hydrogen peroxide decomposes.
What is the definition of catalysis?
Catalysis is the action to increase the reaction rate of a chemical reaction using substances called catalysts which are not transformed during this reaction.
What undergo no chemical change during a chemical change?
Catalysts doesn't undergo a chemical change during a chemical reaction.

Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.

Catalysts speed chemical reactions but are not change by them?
True. A catalysts job is to increase the rate of reaction, but it must do so without (a) being changed by the reaction or (b) become incorporated into the final product.
What does catalysts and rate of reaction do?
Catalysts either accelerate or reduce the rate of the reaction.
What effects does catalysts have to rate of reaction?
In the presence of catalysts the rate of reaction is higher.
Are catalysts required for a chemical change to take place?
They are not essential to cause a chemical reaction.
What is the definition of catalysis?
Catalysis is the action to increase the reaction rate of a chemical reaction using substances called catalysts which are not transformed during this reaction.
