Catalysts are very effective and economical in industrial area. Catalysts increase the rate of a reaction by reducing the activation energy of the reaction. activation energy is the overall energy needed for a reaction to initiate. Both reactions such as exothermic or endothermic has activation energy, so we need to overcome the activation energy for the reaction to proceed. Actually the way it works is quiet simple, it absorbs the reactant particles on its surface reducing their bond energy. When the energy between bonds is weaker, its easier for reactant particle to change to products. Activation energy comes from when reactant particles collide with each other with high kinetic energy.

What substances change the speed of your reactions?
Catalysts accelerate chemical reaction. Enzymes are examples of catalysts that speed up reactions in the body.
All chemical breakdown processes in cells directly involved?
reactions that are controlled by catalysts
How do enzyme and catalyst differ?
they both speed up chemical reations. catalysts work by lowering a reation's activation energy.enzymes speed up a chemical reactions that take place in cells. they both speed up chemical reations. catalysts work by lowering a reation's activation energy.enzymes speed up a chemical reactions that take place in cells.
What are proteins that speed up chemical reactions in organisms called?
We call these enzymes but there are ones in chemical reactions which do the same but are called catalysts.
Enzymes are catalysts. This means that they are able to speed up chemical reactions. statements is also true of enzyme catalysts?
Yes, it is correct.
Speed up chemical reactions?
Catalysts
What effects do catalysts have on chemical rections?
Catalysts generally speed up chemical reactions.
Catalysts?
These are the chemicals that speed up chemical reactions.
How do catalysts differ from inhibitors?
Inhibitors slow down chemical reactions. Catalysts speed up reactions.
What substances change the speed of your reactions?
Catalysts accelerate chemical reaction. Enzymes are examples of catalysts that speed up reactions in the body.
How are catalysts used?
Catalysts are used to speed up the chemical reactions. By usama javed
What speeds up chemical reactions by lowering activation?
Enzymes are the molecules that speed up chemical reactions, and these are forms of catalysts.
What speeds up chemical reactions by lowing activation energy?
catalysts or enzymes which speed up chemical reactions in organisms
How enzymes speed up chemical reactions?
by acting as organic catalysts
What are the substances that increase the rate of a chemical reaction called?
A catalyst can speed up a chemical reaction. Another possible answer in the Biological sense is that Enzymes speed up chemical reactions, but these enzymes are catalysts of the chemical reactions.Different catalysts catalyse different reactions. For example iron is used as a catalyst in the Haber process (manufacture of ammonia).
What molecules speeds up chemical reactions by lowering activation?
Enzymes are the molecules that speed up chemical reactions, and these are forms of catalysts.
What a relationship exists between an enzyme and a catalyst?
they both speed up chemical reations. catalysts work by lowering a reation's activation energy.enzymes speed up a chemical reactions that take place in cells. they both speed up chemical reations. catalysts work by lowering a reation's activation energy.enzymes speed up a chemical reactions that take place in cells.
