Q: Organic chemical concentration of bromine and liquid bromine What is the difference between the conditions in the iron as a catalyst can not be reacted with toluene to produce tribromotoluene? Is it possible to work with phenol to produce tribromophenol?: The concentrated bromine water is a bromine aqueous solution and the liquid bromine is pure bromine. Only liquid bromine can produce tribromotoluene, and to add iron powder as a catalyst, and the main production is to lead bromotoluene and p-bromotoluene, tribromotoluene this content is very small.

Q: The best use of chemical catalysts: Do not know what you want to use the best thing is what the catalyst is generally used in the process, there will be an initial induction period, the catalytic activity is relatively low, and then reached a stable catalytic state, this paragraph is generally called the catalyst life, the final Due to poisoning, active ingredient aggregation and so on factors, the catalyst activity will be reduced, then need to replace the new catalyst

Q: why is palladium/platinum a good catalyst?: Palladium and platinum are good catalysts because they _adsorb_ certain molecules, especially gases. Adsorption is NOT the same as _absorption_. Adsorption is a process by which a chemical (gases or liquid) physically becomes attached to the _surface_ of an adsorbate (a solid). Once gas molecules are adsorbed on the surface of a catalyst, they are much nearer each other and more likely to react. Absorption is a process by which a gas or liquid is incorporated throughout the volume of an absorbate (a solid), rather than just on the surface. The fact the palladium happens to _absorb_ hydrogen molecules well probably has little to do with its function as a catalyst and is probably just a coincidence. In fact, two of the main reactions in a catalytic converter don't involve molecules with hydrogen atoms at all. On the other hand, WHY platinum and palladium are good catalysts are a mystery. Presumably, they are good at enhancing the Van der Waals forces that cause adsorption with other molecules, but WHY the platinum family of metals do this better than other metals is not fully understood (I don't think).

Q: Also, how is the catalyst affected by heat? Please answer all of the questions not just one of the three. THANK YOU!: It denatures the catalyst because the rise in pH or amount of H3O+ ions. Temperature will also denature the catalyst if it's out of its optimum range.

Q: What are the catalysts that appear in the chemistry experiment?: Hydrogen peroxide, manganese dioxide

Q: i know that the catalyst is not react in an reaction,,,so that i don't why could it speed up the reaction?? Further, how does the scientist determine the catalyst for certain reaction??please give me more example....i really want to know it! i do not have any idea about this...so hope your answer will help me....thanks!: Normal reaction requires much heat and energy but a catalyst provides a space where it can be done without either since provides space for both to bump into each other and stay till they bond..so catalyst is not involved in reaction but allowed it to occur at a much lower temp and energy.

Q: Is it possible for the different chemical reactions to have the same catalyst?: Just as manganese dioxide can catalyze the decomposition of molten potassium chlorate can catalyze the decomposition of hydrogen peroxide, but this is not necessarily the same as the catalyst for the production of the same product, but for the enzyme in order to ensure that the growth of the orderly all have a single Enzymes can only catalyze an organic matter

Q: I know that a species that does not appear in the chemical equation may also affect the rate of a reaction - e.g. a catalyst. But does that mean the catalyst can be present in the rate equation, and if so are catalysts always present in the rate equation?: There are many reactions that would not happen to any extent without a catalyst, yet I have never seen a rate equation that included a catalyst. For example, the Haber reaction requires a catalyst, but the rate equation for it does not include a catalyst. If a reaction will work without a catalyst, you can find its rate under this condition. Then if you run the same reaction with a catalyst you will get a different rate of reaction but the catalyst concentration does not show up in the Rate law for that reaction.

Q: In biology, the enzyme seems to be a tool for opening a reaction, such as the decomposition of cellulose, such as linked RNA and protein, no enzyme can not. But in chemistry, the catalyst is only a regulatory role, change the reaction rate only. The teacher said that the enzyme is the catalyst. Is there any other effect of the enzyme? (Ignorant high three dogs, you do not spray the big god): I do not know the main high school teachers have done with fresh chicken liver grinding solution and ferric chloride solution compared to the decomposition of H2O2 catalytic efficiency of the experiment, the result is ferric chloride plus H2O2 slowly take the bubble, add fresh chicken cups Quickly take bubbles and liquid spill. Indicating that the enzyme is a catalyst, and the catalytic efficiency is far higher than the inorganic catalyst.

Q: Write a chemical formula in a chemical laboratory without the use of a catalyst for oxygen: 2KMnO4 = K2MnO4 + MnO2 + O2 ↑ ~ conditions are heating
