Catalysts are chemicals that alter the rate of a chemical reaction without being chemically changed themselves . However to alter the rate of the reaction , the catalysts need to come in contact with the reactant particles. Spreading out the catalyst increases its surface area , hence increases the chances of coming in contact with the reactant particles . So they are able to provide the reactant particles an alternative route with a lower activation energy for the reactant particles to collide and form the product .

What is the truth about catalysts?
Catalysts help chemical reactions: the activation energy is lowered, the reaction rate is accelerated. Catalysts are not exhausted in the reaction and are recyclable.
How do catalysts affect the reaction s in living things?
A catalysts speeds up the reaction in living things.
Substance that speeds up the rate of chemical reaction?
Substances that speed up the rate of reaction are called catalysts. Catalysts participate in chemical reaction but does not get consumed. Yeast is an example of biological catalyst.
How is a catalysts different from a reactant?
a catalyst can affect the rate of a reaction. speeding it up.
What are catalysts that slow down a reaction?
The catalysts can be used to increase or decrease the speed of a chemical reaction. The catalysts which reduce the speed of a reaction are called negative catalysts. They decrease the speed of the reaction by increasing the activation energy of the reaction.
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.

Is it proteins and catalysts that speed up the rate of a reaction?
Catalysts
How do catalysts affect the reaction s in living things?
A catalysts speeds up the reaction in living things.
What are facts about catalysts?
Some of the facts are: 1. Catalysts never get consumed in a reaction 2. Catalysts lower the activation energy of the reaction by providing an alternative path to it. 3. Some catalysts do not take part in reaction. They just provide surface or sites for the reaction to take place.
What function do catalysts perform in chemical?
catalysts speed up a reaction
