Q:Which of the following statements is not true of a catalyst?
the way these choices are written they are all true but the answer could be B
Q:CO and NO react under the action of a catalyst to generate chemical formulas for CO2 and N2.
Landlord's question should not know how to match it, with the loss of electronic with a constant match
Q:What is the catalyst for high chemistry?
Concentrated sulfuric acid, NI, barium bromide, copper or silver
Q:The properties of scandium
Sci-Scandium (Sc) Basic knowledge Introduction In 1879, Swedish chemistry professor Nelson (LFNilson, 1840 ~ 1899) and Clive (PTCleve, 1840 ~ 1905) were almost simultaneously in rare mineral silica beryllium yttrium and black The mine found a new element. They named this element "Scandium" (scandium), ...
Q:Describe the role of a catalyst..........?
a catalyst lowers the activation energy of a reaction. By lowering the activation energy, the internal kinetic energy the reactants become sufficient for the reaction to occur on a much larger scale and thus appear faster. Without the catalyst, you would depend on the statistical probabilities of small numbers of reactant particles having enough internal kinetic energy to overcome the activation barrier. a substrate is merely the substance in the reaction being catalyzed
Q:If the college entrance examination questions related to whether the catalyst involved in the reaction, how should I answer.
The catalyst was involved in the reaction, but the physical and chemical properties did not change before and after the 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 are the requirements for the catalyst for the chemical industry?
Generally find a few, according to the cost and cost of cost, choose cost-effective
Q:The addition of the catalyst has no effect on the chemical equilibrium of the movement
The essence of chemical equilibrium is a dynamic equilibrium. Under certain conditions, the equilibrium constant of the reaction is a certain value. The role of the catalyst is to reduce the activation energy required for the reaction, increase the number of activated molecules, and increase the number of molecules per unit time , But the positive reaction is positive for the reaction, so do not change the speed.
Q:How to write a catalyst main character?
Ways to be a catalyst: By his behaviour: - He is a good listener. People use him as a sounding board and make important decisions as a result. - He is indiscreet and inadvertently reveals people's secrets and back-sniping comments. - He is a ****-stirring gossip. - He is a home-wrecking Lothario. - He is wise and gives good advice. - He is a hooligan who ruins businesses with vandalism, costs people their jobs and ruins relationships by beating people up. - He is a manipulative, blackmailing bastard who tries to turn every woman into a prostitute and con every man out of his money. - He is a charlatan who preaches nonsense about religion, health and business investments. By effortlessly influencing other people's behaviour: - He is famous and people try to impress him wherever he goes. - He has cancer or a disabling war wound. People admire and pity him and are shocked by his PTs mood wings. - He is gay, Muslim or a suspected paedophile and people want to persecute or cure him. - He is destitute. People argue amongst themselves over whether it's because he's lazy, has bad karma or there but for the grace of God go I. - He really looks like Jesus, Buddha or Santa and the sight of him makes people contemplate their Humanist values, coming to various conclusions. Perhaps you can write about his reputation; how he earned it, how it precedes him and provokes prejudices that he sometimes confirms or disproves. Use a detached, omniscient God-narrator. (Pretend Morgan Freeman's reading the audiobook.) Alternatively perhaps he is not a catalyst but a neurotic voyeur, fascinated by the minutiae of other people's lives so that the mundane appears tumultuous. He is not influencing people but your account of the changes in people's lives are centred on his observation of them.
