Q:What makes an enzyme a catalyst?
D: it quickens a chemical reaction yet isn't completely replaced by skill of the reaction this is a standard definition of the understanding catalyst that a biologist gave: A chemical/substance that alters the fee of a chemical reaction yet isn't used up interior the technique.
Q:What does what does catalyst mean?
a catalyst enables a reaction to occur quicker, by lowering the activation energy, and finding it an alternate path way to react. example of a catalyst is an enzyme, found in our saliva, it helps us digest our foods, by breaking it down into smaller pieces.
Q:What is the chemical catalyst for CAT12
(Cat1, cat2, cat4 and cat5) in the presence of terephthalic acid,
Q:The role of catalyst in chemical reactions
The role of the catalyst is to change the reaction required to achieve the activation energy, can reduce the activation energy is called positive catalyst (that is, usually the meaning of the catalyst), to improve the activation energy is negative catalyst
Q:catalyst question?
It makes a reaction run faster and better AND it is not used up by the reaction
Q:What is the similarity between enzymes and general chemical catalysts?
(1) The enzyme is the same in many respects as a biocatalyst and a general catalyst, such as a small amount and a high catalytic efficiency. As with the general catalyst, the enzyme can only change the rate of chemical reaction and does not change the equilibrium of the chemical reaction It is possible to catalyze the activation of a large number of substrates in a short time and to reflect the high efficiency of enzyme catalysis.The enzyme can reduce the activation energy of the reaction (activation) (△ G) during the reaction, but the reaction rate is accelerated and the reaction time is reduced, but the equilibrium constant is not changed. (2) However, the enzyme is a biological macromolecule (1) Enzyme-catalyzed high efficiency: The catalytic effect of the catalyst can increase the reaction rate by 10 ^ 6 ~ 10 ^ 12 times, which is at least several times higher than that of the conventional catalyst. (2) The enzyme catalyst Highly specificity: including specificity of response, substrate specificity, chirality specificity, geometric specificity, etc., that an enzyme can only act on a certain class or a specific substance. Bond, ester bond, peptide bond and so on can be catalyzed by acid-base hydrolysis, but the hydrolysis of these chemical bonds are different, respectively, the corresponding glycosidase, esterase and peptidase, that is, they were specific (3) enzymatic reaction conditions are mild: enzymatic reaction is generally carried out in aqueous solution of pH = 5 ~ 8, the reaction temperature range is 20 ~ 40 ℃
Q:Why are enzymes classified as organic catalysts?
a catalyst is something that makes a reaction go faster than it normally would. An enzyme is a catalyst; it has all the parts for the reaction on it and help organic materials break down or transfer energy or whatever reaction it needs.
Q:High school stage which organic chemical reactions do not use catalyst
Aldehyde and silver ammonia solution reaction, and the new system of Cu (OH) 2 reaction.
Q:What is the difference between a catalyst and an oxidizing agent?
A catalyst alters the rate of a reaction without being used up in the reaction. An oxidising agent oxidises other compounds, the agent itself being reduced in the process.
Q:What is the definition and function of the catalyst in chemistry?
Definition: in the chemical reaction can change the chemical reaction rate of other substances, and its own quality and chemical properties before and after the reaction did not change the material called catalyst, also known as catalyst. The role of the catalyst in the chemical reaction is called catalysis. The use of a catalyst only changes the rate of chemical reaction and does not alter the quality of the product.
