Q: Is it faster or slower? The What if you do not?: The catalyst is divided into: positive catalyst and negative catalyst, positive catalyst accelerates the reaction rate, and negative catalyst slows down the reaction rate. Regardless of the positive and negative of the catalyst, it only changes the rate of the reaction, does not change the nature of the reaction, and the reaction, the chemical nature of the catalyst will not change!

Q: The chemical equation of heating reaction of benzene and hydrogen under the action of catalyst: C6H6 benzene + 3H2 - (arrow) C6H12 cyclohexane (Ni catalytic heating)

Q: Why can't catalysts make an unfavorable reaction favorable?Can anyone give me a relatively simple explanation for this?Thank you so much in advance!: Catalysts, as enzymes, only change the activation energy (the energy the compound needs to gain to transform into products), they don't change the Gibbs energy values of reactants nor products. Therefore, if the delta G of the reaction is positive, it'll still need free energy to complete. They make a reaction complete faster than in normal conditions, but don't change the actual possibility for that reaction to happen. In the human body, a lot of reactions of catabolism have a positive G value and these reactions needs to get energy from other coupled reactions that have a negative value, so the total value is still negative. Many of them use hydrolysis of ATP to provide that energy, as its hydrolysis is about -30 kJ/mol in physiological conditions. I don't know what class you're in to ask this question, so can't really know if this answer is too simple or complicated for u... sorry in advance! Jo?l

Q: It is best to tell me what the role of sulfuric acid in these reactions, respectively: Esterification reaction (dehydration), nitration (dehydration, concentrated nitric acid), carbonation reaction or dehydration reaction (organic matter in sulfuric acid blackening, dehydrating agent), sulfonation reaction (dehydrating agent), ethylene (dehydrating agent).

Q: Please make it simple because I need it for school and please give to examples for the second part Thanx :D: 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: Will the catalyst in the chemical reaction be reduced?: The amount of catalyst in the chemical reaction is not reduced, the catalyst is divided into a positive catalyst and a negative catalyst, the positive catalyst promotes the reaction, and the negative catalyst inhibits the reaction

Q: Can manganese dioxide be used as a catalyst for various chemical reactions?: Catalyst in the reaction process involved in the reaction, after the completion of the reaction was reduced to the original ingredients.For example: heating decomposition of potassium permanganate when added potassium permanganate potassium potassium permanganate decomposition process, the potassium permanganate is involved in the reaction, The specific way is not clear.Finally, the occurrence of potassium permanganate before and after the reaction of the catalyst changes in morphology, particles into powder, powder particles and so on.

Q: what is the difference between enzyme and catalyst?: Enzymes and catalysts both affect the rate of a reaction. The difference between catalysts and enzymes is that while catalysts are inorganic compounds, enzymes are largely organic in nature and are bio-catalysts. Even though all known enzymes are catalysts, all catalysts are not enzymes. Moreover, catalysts and enzymes are not consumed in the reactions they catalyze. Catalysts are low molecular weight componds, enzymes are high molecular globular proteins. Catalysts are inorganic, enzymes are organic. Catalyst reaction rates are slower (usually) than enzyme reaction rates. Catalysts are not generally specific - enzymes are VERY specific. Catalysts increase or decrease the rate of a chemical reaction, enzymes are proteins that incrase the rate of chemical reactions & convert the substrate into product. There are 2 types of catalysts - (positive & negative), and the 2 types of enzymes are activation enzymes and inhibitory enzymes. Catalysts are simple inorganic molecules, while enzymes are complex proteins.

Q: It's a GCSE Chemistry questionI just need to know why there are so many: Many important chemical reactions require inputs of energy to proceed. If a catalyst is present less energy will be required to complete the reaction. Catalysts are substances that are mixed in with materials that are to be reacted, but they themselves do not, in the end, change chemically. They establish a local environment that promotes one or more chemical reactions to take place. A catalyst is important in many industrial processes. Sulfuric acid, which is used to produce batteries, detergents, dyes, explosives, plastics, and many other produces, is commonly produced using a catalyst called vanadium oxide. Ammonia, a primary component of many fertilizers, could not be produced economically without the use of iron oxide which speed up the reaction. The process of catalyst also affects the state of our global environment. Automobiles use catalytic converters to treat exhaust. The metals platinum and palladium facilitate the chemical conversion of noxious gases to more inert forms, greatly decreasing the environmental impact of combustion engines. Probably the most important impact of catalyst is on life itself. All important biochemical reactions are catalyzed by molecules called enzymes. Most enzymes are proteins which catalyze specific reactions within cells. Some examples include polymerases, which synthesize DNS and RNA, peptidases, which digest protein, and ATP synthases, which produce energy for the many different cell activities.
