Q:Chemistry: Does the catalyst participate in the reaction?
The catalyst does not participate in the reaction, except that the reaction rate is changed.
Q:Chemical reaction in the presence of catalyst for the reaction are carried out a high life
Juvenile high school you have to learn the reaction are hundreds of I can not tell you one by one you will learn some of the time can be added plus no plus can not respond
Q:how could scientists know the exact catalyst for every reactions??? THANX sooo much
Believe me, nema, there's no way that we chemists know the best catalyst for every reaction. That would be simply impossible. However, from the type of reaction, the reactants, products, reaction conditions, solvents, etc. and from one's experience and the literature (papers and patents) one can get a good idea for most reactions of the type of catalyst that has worked for similar systems. One then starts off with a catalyst from the literature and modifies or changes it if improvement is needed based on chemical principles that one learns. There are also some theoretical calculations that can be made. Sometimes they work and sometimes they don't :) If it is an industrially important process like the Haber process for making ammonia from nitrogen gas and hydrogen gas, there may be thousands of catalysts which have been tried and evaluated. New minor improvements are being made every day. When a company does find a very good catalyst for an important reaction, often they keep it a trade secret. The good catalyst can make a huge difference in how commercially successful a particular process is. That's a large part of what chemical engineers do. You may never know if you have the best catalyst. The most you can hope for is one that is good enough. So it's a few parts personal knowledge, a few parts literature, a couple of parts theory, a lot of experimentation and often, more than not, a little luck. :)
Q:If the college entrance examination questions related to whether the catalyst involved in the reaction, how should I answer. (We must college entrance examination, I hope you help out, thank you.)
The catalyst does not participate in the reaction, but only to accelerate, slow down the auxiliary role
Q:Does the catalyst affect the chemical reaction rate constant? How does the chemical reaction rate constant change when a positive catalyst is added to a reaction?
The catalyst will change the rate constant
Q:Can manganese dioxide do any catalyst for chemical reactions?
The catalyst is selective
Q:and what type of macromolecule are they made of? thanks!
by definition a catalyst is a substance that alters the cost of, or makes accessible, a chemical or biochemical reaction yet maintains to be unchanged on the tip of the reaction. Enzymes are the only organic biochemical catalysts. Ribozymes are a particular sort of enzymes. certainly, the definition of enzyme rates: organic and organic catalyst produced in cells, and able to dashing up the chemical reactions mandatory for all times. they're great, complicated proteins, frequently soluble, and are noticeably specific, each and every chemical reaction requiring its very own specific enzyme. The enzyme's specificity arises from its energetic website, a community with a shape such as portion of the molecule with which it reacts (the substrate). the form of the enzyme the place the chemical binds in straightforward terms facilitates the binding of that distinctive chemical, such as a particular key in straightforward terms working a particular lock (the lock and key hypothesis). The enzyme and the substrate slot jointly forming an enzyme–substrate complicated that facilitates the reaction to ensue, and then the enzyme falls away unaltered. In prepare maximum catalysts are used to velocity up reactions. There are different non-organic and organic catalysts. maximum of that are utilized in industry and are commonly transition metals or their compounds.
Q:Now, i am studying for my biology exam in 3 weeks time...i stumbled upon catalase, and then checked my book its catalyst...now im confused...is there a different among these 2 terms? i think..catalyst is the when a substance brings up or about a chemical reaction without using itself up and then catalase breaks down the toxic by-product of metabolism, hydrogen peroxide, into water and oxygen.Or am i wrong?please explain what is catalyst and catalase in biology or are they the same, just differently?
an enzyme that decomposes hydrogen peroxide into oxygen and water.a substance that causes or accelerates a chemical reaction without itself being affected. To put thing simply, a catalyst is any substance that speeds up a chemical reaction. These can be natural or manmade. Catalase is actually a specific type of naturally-occuring catalyst, an enzyme in cells that decomposes hydrogen peroxide (Which is extremely toxic to life!) into harmless components. Catalase enzymes are highly concentrated in the aptly named cell organelles known as peroxisomes. Just remember- if the word ends in -ase, it's a type of enzyme! :) Hope this information helps!
Q:What is the relationship between the catalyst and the chemical reaction? What is the relationship between the enzyme and the catalyst?
Enzyme is a biocatalytic biological biomolecule, a biocatalyst that accelerates the rate of biochemical reactions without changing the direction and product of the reaction. That is, enzymes can only be used to change the speed of various biochemical reactions, but not the biochemical reaction itself. Enzyme is a kind of amino acid composed of a special biological activity of the substance, which exists in all live animals and plants, is to maintain the normal function of the body, digest food, repair tissue and other life activities of a necessary material.
Q:The quality and nature of the catalyst before and after the chemical reaction did not change this sentence wrong? Why did the "middle school student study" say it was wrong?
This sentence is true, ah, may practice mistakes in the bar.
