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.

What effect does a catalyst have?
a catalyst has no effect in chemical reaction. it only increases or decreases the rate of the chemical reaction.
What happens to the reaction rate when a catalyst is used in a chemical reaction?
With a catalyst the reaction rate is higher.
What will change when a catalyst is added to a chemical reaction?
A catalyst speeds up the rate of reaction, and lower the activation energy needed.
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.
What do catalyst substances do to the rate of a chemical reaction?
increase

What happens to the reaction rate when a catalyst is used in a chemical reaction?
With a catalyst the reaction rate is higher.
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.
How does catalyst effect chemical change?
A catalyst alters the rate of a chemical reaction.
Is catalyst a product of chemical reaction?
No a catalyst is unchanged by a chemical reaction, it does however serve to speed up the rate of the reaction.
What accelerates the rate of a chemical reaction?
a catalyst
What will change when a catalyst is added to a chemical reaction?
A catalyst speeds up the rate of reaction, and lower the activation energy needed.
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 effect of a catalyst on a chemical reaction?
To Cause a Chemical reaction. A properly chosen, specific catalyst is able to speed up the rate of a particular chemical reaction.
A substance that speeds up rate of a chemical reaction?
Catalyst, biocatalyst or enzyme.
What is catalsts'?
Catalyst alter chemical rate of reaction
What is a substance that accelerates the rate of a chemical reaction?
a catalyst
