5.FAQ

We have organized several common questions for our clients，may help you sincerely：

①How about your company？

A world class manufacturer & supplier of castings forging in carbon steel and alloy steel，is one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

②How to guarantee the quality of the products？

We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

③How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers.Commonly 7 to 10 working days can be served.

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: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.

Q:put in a way that a freshman in high school can understand please =): which of the following statement apply both to enzymes and to any other catalysts: their activity is stopped by high temperature. they speed up chemical reaction. they are proteins. they are not used up during the reaction

Q:How does catalyst aid a chemical reaction?: A catalyst works by providing an alternative reaction pathway to the reaction product. The rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst. Catalysts generally react with one or more reactants to form an intermediate that subsequently give the final reaction product, in the process regenerating the catalyst. The following is a typical reaction scheme, where C represents the catalyst, X and Y are reactants, and Z is the product of the reaction of X and Y: X + C → XC (1) Y + XC → XYC (2) XYC → CZ (3) CZ → C + Z (4) Although the catalyst is consumed by reaction 1, it is subsequently produced by reaction 4, so for the overall reaction: X + Y → Z As a catalyst is regenerated in a reaction, often only small amounts are needed to increase the rate of the reaction.

Q:What is the meaning of catalyst in chemistry?: In the chemical reaction can change the reaction rate of chemical reaction (increase or decrease) without changing the chemical balance, and its own quality and chemical properties in the chemical reaction before and after the material did not change the catalyst.

Q:High school knowledge __ teacher do not know right!: Nothing to do, but with the percentage of activated molecules, is proportional to

Q:What is the microcosmic principle of the catalytic reaction in the chemical reaction?: It is actually directly involved in the reaction, but, after the reaction, it has become a product out, the equivalent of no response

Q:What is a catalyst and how does it make a reaction go faster?: Catalysts change the rate of the reaction (faster / slower) without being consumed (used up) in the reaction. They do this by providing a lower energy (easier) pathway from reactants to products. For example in the reaction A + B -D, we can split up the reaction into the two half-reactions below. The first describes the two reactants coming together and the second describes the product formation. A + B -AB AB -D If we add a catalyst which both A and B bond to easier than they do to each other this can increase the rate of the reaction by bringing A and B together on the catalyst. This can be represented with the half-equations below. A + B + Cat -ABCat ABCat -D + Cat

Q:What is the principle of catalyst reaction rate in chemical reactions?: Can significantly change the reaction rate and its own chemical properties and quantity in the reaction before and after the basic material unchanged. The catalyst has a positive catalyst (i.e., accelerates the reaction rate) and a negative catalyst (i.e., reduces the reaction rate), and generally does not specifically refer to both the positive catalyst.

Q:My chemistry teacher wont tell me because it's in the higher course. And i'm not waiting a whole year to find out. And also, google is being a gimp about it. So thanks a lot if you know, I only have basic chemistry knowledge btw, lumen'ss terms if you can.: Catalysts facilitate the reaction. They might work in several ways. Here is an example: Catalysts generally react with one or more reactants to form intermediates that subsequently give the final reaction product, in the process regenerating the catalyst. The following is a typical reaction scheme, where C represents the catalyst, X and Y are reactants, and Z is the product of the reaction of X and Y: X + C → XC (1) Y + XC → XYC (2) XYC → CZ (3) CZ → C + Z (4) Although the catalyst is consumed by reaction 1, it is subsequently produced by reaction 4, so for the overall reaction: X + Y → Z They might also just increase the surface area, thus speeding up the reaction. Example: Coke looses its fizz over time if left with the cork unscrewed. This is because the HCO3 is released as CO2. If you drop a menthos into the coke, it explodes with CO2, because the methos is full of tiny dents in the surface (thus giving it a massive surface area). (i blatantly copied the first example from the wiki)
