it can also speed up a reaction. simply a catalyst can change the rate of a reaction, both slow and increase rate
What else can I help you with?
Why does a catalyst speed up the rate of reaction?
The use of a catalyst increases the chance of particles meeting. This causes there to be a decrease in activation energy, and results in an increase in rate of reaction.
What happenes to the speed of a chemical reaction when a catalyst is present?
The speed of a chemical reaction may increase or decrease by the addition of a catalyst. In the synthesis of ammonia by Haber's process , Fe + Mo mixture acts as a catalyst which increases the formation of ammonia,here Fe + Mo mixture is positive catalyst(increases the speed of the reaction). The oxidation of chloroform (CHCl3) by air in presence of sunlight is retorted by the edition of 1% ethyl alcohol in to it. Here alcohol acts as a negative catalyst (decreases the speed of the reaction)to the oxidation of chloroform .
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.
Why can a catalyst speed up a reaction even at low temperature?
Because catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction increases.
What it will change adding a catalyst to a chemical reaction?
Adding a catalyst to a chemical reaction can increase the rate of the reaction by providing an alternative pathway with lower activation energy. This allows the reaction to occur more quickly without being consumed in the process. Essentially, a catalyst speeds up the reaction without being permanently changed itself.

What is the difference between positive catalyst and negative catalyst?
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.
Why can a catalyst speed up a reaction even at low temperature?
Because catalyst will reduce the activation energy of the reaction, thereby the speed of the reaction increases.
How does a catalyst affect the speed of a reaction?
A catalyst enables more particles to reach the activation energy and to take part in the reaction. Therefore the speed of the reaction increases.
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.
Which component is affected when a catalyst is added to a chemical reaction?
The component affected when a catalyst is added to a chemical reaction is the reactants. The purpose of a catalyst is to speed up a reaction.

What does a biological catalyst do?
they speed up a reaction
What can be added to a reaction to speed it up?
A catalyst
