Catalysts does not alter the reaction at all but only speeds up the reaction. In an equilibrium reaction it speeds up the rate of reaction in both direction, forward and backward reactions. It actually absorbs the reactant particles into its surface and weakens their bonds. Reaction proceeds when the activation energy is overcomed. In the reactant side, particles collide with each other with high speed.

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.
Why are catalysts spread out in a reaction?
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.

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 enzymes altered in the process of catalyzing chemical transformations?
they alter their shape in the process, but come unaltered at the end of the reaction (one of the main characteristics of 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.
Is it proteins and catalysts that speed up the rate of a reaction?
Catalysts
Each enzyme produced by the body is?
Biological catalysts. They alter the speed of a reaction without undergoing permanent changes themselves.
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
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.
