- Q: Chemistry GCSE what is a catalyst?
- A catalyst is a substance added to a reaction to speed the reaction up!
- Q: What is a catalyst and how does it make a reaction go faster?
- a catalyst is a substance that increases the rate of a chemical reaction, but is chemically unchanged at the end of the raction. the process is known as catalysis. calalysts work by lowering the activation energy of the reaction.
- Q: Always speeds the reation ratedoes not affect the reation rateundergoes a chemical changedoes not become part of the chemical changealways slows the reation rate
- A catalyst does not ever become part of the chemical change. As far as I know, it always speeds up the reaction, but I could be wrong on that if there is only one correct answer. For sure, it's never changed by the reaction. That is part of a catalyst's definition.
- Q: What is the catalyst condition in the chemical equation?
- I studied three methods ~ word which can be used to give me a mailbox to the word text to pass you ~
- Q: To write a 1500 words of small papers, so please help you busy
- Change the course of the reaction
- Q: What is the difference between an enzyme catalyst in a living body and a catalyst in chemistry?
- in vivo enzyme activity is regulated in the body, the enzyme activity is regulated control. This is another important feature of the enzyme that distinguishes it from the chemical catalyst. There are many ways to regulate enzyme activity, such as feedback regulation, covalent modification, zymogen activation, allosteric regulation, hormone regulation, and so on.
- Q: The beginning of the chemistry plus the catalyst and the plot without the Cuihua agent
- Plus the rate of fast
- Q: Effect of Catalyst on Chemical Reaction Rate
- The catalyst can only change the rate of chemical change (faster or slower), does not change its own quality and chemical properties, nor does it change the amount of reaction product.
- 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: Is there a catalyst in the chemical shop?
- If it is manganese dioxide what is sold because it is not dangerous not expensive
