- Q: On the issue of chemical balance and catalyst
- The catalyst also changes the forward and reverse reaction rate.
- Q: What is positive and negative catalyst in chemistry?
- Negative catalysts are, on the other hand, slowing down the positive reaction rate at the same time
- Q: describe a biological catalyst?
- Enzyme are biological catalyst, proteinous in nature, formed in animal's body by exocrine cell, present in inactive form, generally ends with suffix ase e.g enterikinase with exceptions pepsin, specific in nature not only speed up biological reactions but also lower down the reactions inside the body.
- Q: Does the catalyst slow down the chemical reaction rate? Still can only accelerate
- The role of the catalyst is to change the activation energy to achieve the purpose of changing the reaction rate, there is a rate of response to speed up the rate of slow response
- Q: What is the definition and function of the catalyst in chemistry?
- The catalyst plays an important role in chemical production. For example: in the oil refining process, the use of high-performance catalyst into gasoline and no other; in the car exhaust treatment process, with the catalyst to promote harmful gas conversion ...
- Q: about 1-3 sentences on this will do thank you
- A catalyst is a compound that participates in and increases the rate of a chemical reaction without being chemically altered itself. These reactions can be anything from inorganic reactions in fuel cells facilitated by metal catalysts, to the breakdown of glucose in cells by a series of biological catalysts. Biological catalysts operate in biological systems made up of organic molecules (and are made up of organic molecules themselves - mostly carbon)... thus it's logical to think of enzymes as organic catalysts.
- Q: What is the difference between an enzyme catalyst in a living body and a catalyst in chemistry?
- (Such as: high temperature, high pressure, strong acid, alkali, etc.), but the enzyme catalyzed reaction (enzymatic reaction) is generally at room temperature, atmospheric pressure (normal reaction), the reaction temperature of the chemical reaction, , Neutral pH, etc. under mild reaction conditions.
- Q: Why can some catalysts be reused in (chemistry)?
- Because the catalyst in the chemical reaction before and after the quality and chemical properties have not changed, so in the chemical reaction can be reused.
- Q: When you write a chemical equation, how do you want to add "catalyst" and "?" When you do not have to write?
- This is the need for your memory, write a few times, will naturally cooked
- Q: Chemistry: Does the catalyst participate in the reaction?
- The catalyst does not participate in the reaction, except that the reaction rate is changed.
