- Q: Why the amount of catalyst is too small will make the chemical reaction rate slowed down
- Whether the chemical reaction can be carried out according to the change of free energy, but only according to the change of free energy can not determine whether the reaction can be completed, because the chemical reaction is also completed by the reaction of the energy barrier, that is, if the reaction energy barrier is high, To provide some energy, across the barrier, to complete the reaction. The energy barrier is called activation energy. And the role of the catalyst is to reduce the activation energy, so that in a relatively harsh environment, chemical reaction occurs.
- Q: What is the principle of the catalyst? Why can change the rate of chemical reactions and their own without any change
- Because the catalyst does not participate in the reaction, it can change the rate of chemical reactions without any change in itself.
- Q: Characteristics and types of catalysts?
- Catalysts don't undergo any change. and types of catalysts - 1) Homogeneous Catalysts ( Having same phase that of reactant, product i.e. reactant and product and catalysts all are either liquid or gas or solid.). 2) Hetrogenrous Catalysts (Different Phase than that of reactant and product. 3) Autocatalysts (reaction proceed catalysed as product is formed or product catalyse the reaction.)
- 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: What is the catalyst in the end?
- You said the chemical catalyst or Ati graphics card catalyst? If the above is enough to explain the above, if it is the latter, that is, the meaning of the graphics card, Ati's graphics drive like a catalyst
- 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?
- The newspaper is wrong and find the teacher's theory. The
- Q: What is the difference between a catalyst and an oxidizing agent?
- A catalyst is a substance that increases a chemical reaction rate without being consumed in the reaction. Heat is probably the most common catalyst. In some cases the reaction will occur without the catalyst but very slowly. In other cases, the reaction will not occur. In the body, enzymes are often catalysts. An oxidizing agent, causes a compound to lose electrons and it is then said that that compound was oxidized. The oxidizing agent gains electrons and is said to be reduced. An example is hydrochloric acid. Is is oxidized by oxygen gas and loses hydrogen atoms leaving chlorine gas. The oxygen gains hydrogen atoms and forms water. The hydrochloric acid is oxidized and the oxygen is reduced.
- Q: Can the catalyst be a reactant in chemistry?
- There is also a saying that the catalyst participates in the chemical reaction. In a general chemical reaction, the effect of the catalyst is to reduce the activation energy required for the reaction to occur, essentially to turn a more difficult reaction into two, In the second reaction, the catalyst in the first reaction plays the role of the reactant, and the catalyst in the second reaction plays the role of the product, so that the catalyst is not present before and after the reaction Variety.
- Q: Manganese dioxide can be used as a catalyst for various chemical reactions
- The reactor may be a reactant,
- 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?
- Catalysts and catalase are two different things, and the definitions that you listed are correct. A catalyst is something that speeds up the rate of a chemical reaction. Many chemical reactions occur naturally and do not require any energy, but they occur so slowly that they are not useful, and catalysts can be used in cases like this to speed up the process. For example iron metal exposed to oxygen and water turns to rust, but if you need a lot of rust by tomorrow, leaving a chunk of iron out in the rain is not a practical solution because it will take too long to convert all that iron metal into rust.
