Q:how does the catalyst work (to speed up the reaction)??
catalyst takes the reaction through an alternate path(series of reaxns) which has lower activation energy.hence it speeds up ur reaction
Q:About the catalyst?
Catalysts are not used/destroyed in any reactions, it merely speeds up the process by lowering the reaction activation energy. It functions by being able to weaken or break the required bonds necessary in the chemical reaction (thus lowering activation energy) through temporary and weak bonding to form a complex. In this case the H2O2 molecule will bind with the MnO2 molecule due to the complimentary sites (thus forming a complex) to weaken the bonds for decomposition, but after decomposition the products (oxygen and water molecules) break off from the catalyst (as there are no more complementary sites with them) thus the catalyst will not be destroyed.
Q:what is a catalysts and how can they be useful?
A catalyst is a substance that speeds up the rate of a chemical reaction with itself being chemically unchanged at the end of the reaction. They are useful as they help to lower the minimum amount of energy needed ( also known as activation energy) to start the reaction. Hence, by lowering the activation energy of the reaction, they help to speed up the rate of reaction. For example, in the Haber process for the manufacture of ammonia, the catalyst iron is added to speed up the rate of reaction between hydrogen gas and nitrogen gas. Otherwise, the reaction would have proceeded much more slowly. Another example is the catalyst nickel used in the manufacture of margarine and vanadium (V) oxide for manufacturing sulfuric acid. As catalyst remain chemically unchanged after a reaction, they can be reused again and hence, they are required in minute amounts. An example is the washing powder used in washing clothes, they help to remove food stains by digesting the proteins in food. They can be reused after each reaction and hence, you do not need to add in the whole packet of washing powder but only a few spoonful.
Q:A question about the catalyst in a chemical reaction
CuO exothermates when catalyzing the decomposition of hydrogen peroxide, so the reaction becomes faster.
Q:Can Cuo react as a catalyst with H2O2, does its quality and chemical properties change?
2H2O2 (CuO catalyzed) ====== 2H2O + O2 ↑
Q:What is the chemical vinyl chloride and benzene plus catalyst?
Ethylbenzene plus hydrogen chloride
Q:What is the PTC catalyst in chemistry?
1, polyether chain polyethylene glycol: H (OCH2CH2) nOH chain polyethylene glycol dialkyl ether: R (OCH2CH2) nOR2, cyclic crown ethers: 18 crown 6,15 crown 5, Fine and so on. 3, quaternary ammonium salt: commonly used quaternary ammonium salt phase transfer catalyst is benzyl triethyl ammonium chloride (TEBA), tetrabutyl ammonium bromide, tetrabutylammonium chloride, tetrabutylammonium hydrogen sulfate (TBAB) , Trioctylmethylammonium chloride, dodecyltrimethylammonium chloride, tetradecyltrimethylammonium chloride, and the like. 4, tertiary amine: R4N X, pyridine, tributylamine and the like. 5, quaternary ammonium base (its alkaline and sodium hydroxide similar) soluble in water, strong hygroscopicity. 6, quaternary phosphonium
Q:Chemical catalyst in several ways
Two, can speed up and slow down
Q:High school stage chemical catalyst
Manganese dioxide and iron are more common, vanadium oxide sometimes encountered, sulfuric acid is also a catalyst, but generally used as a dehydrating agent. Inorganic catalysts catalyze the object is diverse, unlike the organic catalyst as a single, so hard to say. In high school is probably used to prepare oxygen when the use of manganese dioxide
Q:Does the catalyst participate in chemical reactions?
The catalyst only acts as a catalyst in the chemical reaction and does not participate in the chemical reaction
