Different reactions may require different catalysts. Catalysts are specific to certain reactions based on their mechanism and the chemical reactions involved. Different reactions have different activation energies and pathways, so they may require different catalysts to facilitate the reaction.
What else can I help you with?
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.
How many types of catalyst are there?
There are mainly two types of catalysts: homogeneous catalysts, which are in the same phase as the reactants, and heterogeneous catalysts, which are in a different phase. Homogeneous catalysts are usually dissolved in the same solvent as the reactants, while heterogeneous catalysts are typically solid catalysts in contact with the reactants.
How does enzymes speed up chemical reactions?
The way enzymes speed up chemical/biochemical reactions is the same way that catalysts work. They provide an alternate pathway for the reaction which has a LOWER activation energy. They don't actually decrease the activation energy of the pathway in question, but rather they provide a different pathway that has a lower energy of activation.
Is Enzyme have same function called as?
Enzymes have the same function as catalysts. Except, the mode of action is markedly different.
Are enzymes permanently changed in the chemical reactions they aer involved in?
No. Enzymes are not permanently changed in the chemical reactions in which they are involved. After the reaction, they regain their original shape and are free to catalyze another of the same reaction.

What are the two important classes of catalysts?
The two important classes of catalysts are homogeneous catalysts, which are in the same phase as the reactants, and heterogeneous catalysts, which are in a different phase from the reactants. Each class has its own advantages and applications depending on the specific reaction and conditions.
Is Enzyme have same function called as?
Enzymes have the same function as catalysts. Except, the mode of action is markedly different.
Why don't all reactions produce the same amount of products?
all reactions are different. therefore, different amounts of products are produced.
Can ions that come from the same chemical compound have different chemical reactions?
Yes. It is possible when the charge on the ions are different. For example the reactions will be different for Fe2+ and Fe3+
How are exothermic and exothermic reaction are different and how are they the same?
Endothermic and exothermic reactions are similar in that both have reactants and products. They are different in that exothermic reactions release energy through reacting and endothermic reactions absorb it.
Are enzymes permanently changed in the chemical reactions they aer involved in?
No. Enzymes are not permanently changed in the chemical reactions in which they are involved. After the reaction, they regain their original shape and are free to catalyze another of the same reaction.
What are the important classes of catalysts including both the inorganic and biological catalysts?
Catalysts are generally divided into homogeneous and heterogeneous ones. Homogeneous catalysts are in the same phase as the reactants, for instance a mineral acid is added to an aqueous solution of an ester to speed up hydrolysis. Heterogeneous catalysts are in a different phase to the reactants, for instance exhaust gases from a car engine pass over the heated metals of the catalytic converter to speed up their conversion to safer gases. Natural catalysts are called enzymes and are homogeneous.
How do catalysts affect energy of reactions?
Catalysts lower the activation energy required for a reaction to take place by providing an alternative reaction pathway. This allows the reaction to proceed more quickly and with less energy input. The overall energy change of the reaction remains the same, but the rate of the reaction is increased.
Are enzymes and proteins the same thing?
Enzymes are a type of protein that act as biological catalysts to speed up chemical reactions in living organisms. So, while all enzymes are proteins, not all proteins are enzymes.
