PACKAGE:
- Q:give an example of how a catalysts speeds up the rate of reaction?? thank you!!?
- When making margarine, nickel is used to speed up the process.
- Q:Does the catalyst participate in chemical reactions?
- In fact, my understanding is to participate in the reaction, but in the whole process of reaction is both a reactant and a product. But in the reaction process is to participate.
- Q:and can you give me an example of it .. please give it in easy terms if you can. thanks
- A catalyst is something that speeds up a reaction. Heat is a catalyst. An example is the catalytic converter in a car, it speeds up the reaction and makes the fumes coming out not as toxic.
- Q:Palladium is the main catalyst in chemistry?
- Palladium in the chemical mainly to do the catalyst; palladium and ruthenium, iridium, silver, gold, copper and other alloy, can improve the palladium resistivity, hardness and strength, used in the manufacture of precision resistors, jewelry and so on. While the most common and most commercially available palladium jewelery is palladium.
- Q:Describe the role of a catalyst and a substrate in a chemical reaction.
- a catalyst speeds up the reaction
- Q:Where are they good catalysts and why?? THanks!
- A catalyst is a substance that speeds up a chemical reaction by providing an alternate reaction pathway with a lower activation energy. Catalysts appear not to take part in the reaction. Frequently, catalysts are not very reactive. Acids and bases, on the other hand, are very reactive. Acids (as H+) and bases ( as OH-) sometimes function as catalysts in some organic reactions. They appear to be catalysts because in the course of the mechanism H+ or OH- is regenerated.
- Q:hey people i need your help about my science lab report...the question on my paper says "what function the catalyst?....please help me on this one...i would really appreciate if you leave me answers....much mahalos to all you folkss...thanks
- concepts-blowing on Bandit - it converts Carbon monoxide into Carbon Dioxide (besides as emitting risky debris of Platinum, Iridium and tungsten). hang on - Carbon Dioxide - isn't that the ever so nasty greenhouse gas that we are all meant to be reducing our output of? i'm taking my cats off.
- Q:Does the catalyst affect the chemical reaction rate constant? How does the chemical reaction rate constant change when a positive catalyst is added to a reaction?
- The positive catalyst will increase the constant, negat
- Q:What are the methods of catalyst characterization?
- Chemical means, according to the different detection methods, methods are different, but is to explain the chemical properties, chemical structure characteristics.
- Q:What is the catalyst condition in the chemical equation?
- On the middle of the equal sign or arrow above ah ~
